Properties of 17

These pages are no longer updated and I plan to rewrite them. A last news item (Le Monde, May 27, 1998): « The police seized, on Monday, May 25, the 17 little pigs in porcelain Nancy Bennett, an inhabitant of Leicester, in Great Britain, had put on the window ledge in the street of the big mosque: Muslim believers had complained. »

17 in the History

The cave of Lascaux, painted 17,000 years ago, was discovered by Marcel David, 17 years old.

One of the earliest mentioning of the number 17 was by the Egyptians. The Rhind papyrus from 1700BC contained the following 2/17 = 1/2 + 1/51 + 1/68 (which is FALSE! This is the only error in list of expansions of fractions of the form 2/n into sums of unit or Egyptian fractions.)

The mummy of King Tutankhamen was wrapped in 17 sheets.

The Parthenon is 17 columns long.

The Chinese had a bureaucratic constitution with 17 articles.

The Alhambra, a beautiful Moorish palace which inspired Escher, is composed of 17 kinds of mosaics (in fact, all of the possible ones).

Henri IV celebrated his wedding a second time on December 17, 1600, in Cathedral Saint-Jean in Lyon. His wife Marie de Médicis arrived with about 5000 Italians in 17 galleys.

Queen Anne of Great Britain had 17 children who died before their second birthday. Her only son to survive infancy died at the age of 11.

Nostradamus's quatrain 5,92:

Après le siège tenu dix-sept ans,
Cinq changeront en tel révolu terme:
Puis sera l'un esleu de mesme temps,
Qui des Romains ne sera trop conforme.
(cf http://www.infobahnos.com/~ledash/johnpaul.html#).

Shakespeare wrote 17 comedies (in the 17th century). Hamlet reigned for 17 years.

Beethoven wrote 17 string quartets. The first of Händel's Water Music took place on July 17, 1717 (the yellow pigs day!). Domenico Zipoli sailed for South-America in 1717 and landed in July 1717. Gossec wrote a symphony in 17 parts. Titchenko wrote a concerto for cello and 17 wind instruments. Senfl wrote a mass in 17 parts (given on October 2, 1994 at the Festival d'Ambronay). Mendelssohn's op. 54: 17 variations for piano. Bach had an orchester with 17 musicians during the Weimar period, when he wrote the concerto for 2 violins BWV 1043 (France-Musique, Bach et l'Europe, December 10, 1995). In 1895, St-Saens had 17 volumes of Rameau's work published (Radio Classique, December 13, 1995, 15:30). With one of his fiancées, Alessandro Scarlatti had 17 children including Domenico (France-Musique, January 26, 1996); Marin Marais had 17 children (France-Musique, L'éveil des muses, February 3, 1996). In 1575, Byrd and Tallis published the Cantiones Sacrae, dedicated to the Queen: 17 motets by Byrd and 17 by Tallis (from an article in rec.music.early, September 5, 1996). Telemann wrote 17 operas.

Fermat had been working as an agent for 17 years. Then he became a councillor at the Parliament of Toulouse, where he had been working for 17 years.

Gauss (born in 1777) constructed the famous 17-gon at the age of 18, having probably thought about it from the age of 17.

There is a famous passage in Plato's Theaetetus in which it is stated that Theodorus (Plato's teacher) proved the irrationality of sqrt(3), sqrt(5), ..., `taking all the separate cases up to the root of 17 square feet, at which point, for some reason, he stopped'. But we don't know the exact meaning of the Greek word (mu)(epsilon)(chi)(rho)(iota), translated as `up to' by Heath: either `up to but not including' or `up to and including'. (An Introduction to the Theory of Numbers, Hardy/Wright, section 4.5, pp 42-44)

Marconi used 17 patents of Tesla's (cf ST Magazine 75, p 54).

The French revolution took place in 1789 (8+9 = 17).

In Chatou (78400, France), a street is called rue des dix-sept (i.e. street of the seventeens). The extension of rue de Sahüne was given this name in December 1880. In 1878, the town council considered that property Fauchat was suitable to be a future town hall. But the heirs refused to sell the house separately, and the town council didn't want to (or couldn't) buy the whole domain. Mayor Bousson engaged its fellow citizens to form a civil company to buy all of it. This company was constituted by 17 people. It gave the town the house and some land while it sold the surplus by lots, making a profit given to the town. The names and the photos of these 17 are displayed on a board in the town hall. These are Mr. Albin, Barbier, Bardon, Baudry, Blin, Bousson, Coulon, Déjardin, Dijon, Ducellier, Huser, Lambert, Laubeuf, Marais, Sandel, Sarazin and Yvon. Source: tourist bureau of Chatou.

Symbols and Religion

Bible

The number 17 is used 13 times in the Bible: Genesis 7:11, 8:4, 37:2, 47:28; 1 Kings 14:21, 22:52; 2 Kings 13:1, 16:1; 1 Chronicles 24:15, 25:24; 2 Chronicles 12:13; Jeremiah 32:9; Judith 1:13.

The 17th book is the shortest. Someone has spent 17 years looking for the exact middle point of the Bible. It is the psalm 117 which is the shortest. The longest one is the psalm 119 (divisible by 17).

2² + 3² + 5² + 7² + 11² + 13² + 17² = 666 (number of the Beast).

The Flood started on the 17th. Noah's Ark landed on the Mount Ararat (alt. 17,000 feet) on the 17th.

Miscellaneous

In Au bonheur des mots, by Claude Gagnière, ed. Robert Laffont, p 206:

The Italians fear the 17's, because 17 is written XVII in Roman numerals, which is the anagram of VIXI, which means "I lived", i.e. "I am dead". In Italy, buildings do not have a 17th floor, hotels do not have a room 17, and Alitalia planes do not have a seat 17 [neither do Air Inter planes and British Airways Concordes]. When Renault marketed its R17 and wanted to export it to Italy, it had to be renamed "Renault 177". Napoleon Bonaparte, who was more Italian than French in his education, refused to give the signal for his coup on "vendredi 17 brumaire" and postponed it until the following day.

In Dictionnaire des symboles, ed. Robert Laffont / Jupiter (1982), p 360:

This number, as well as 72 (the two being related: 17 being 9+8, 72 being 9×8) presents a high symbolical importance.

In the Islamic tradition, 17 is the number of rak'a (liturgical gestures), part of the five daily prayers. 17 is also the number of words in the call to the prayer. In the Muslim folklore, the symbolical number 17 appears in legends mainly, particularly in the 17 pieces of advice muttered at the king's ear during his crowning and in the 17 parts of the standard (M. Mokri, Les secrets de Hamza).

It is mainly in the Chi'ism (and, because of its influence, in the Turkish epico-religious literature in Anatolia) that a quasi-magical importance is given to the number 17... From the ancient times, the Chi'ist mystics had venerated the number 17; this veneration has its origins in the ancient Pythagorean speculations lying on the letters in the Greek alphabet... 17 represented the number of those who would rise from the dead and each one of those people was to receive one of the 17 letters of the alphabet, making up the highest name of God, which is certainly related to the blade of the Star, arcanum 17 in the Tarot game whose symbolism evokes mutation, rebirth, and which Dr Allendy considers to be Karmic Liberation (alln, 364). Moreover, according to The Book of the Balance by Gâbir ibn Hayyân, an alchemist and a soufi, the shape (sura) of every thing in the world is 17; 17 is the very basis of the theory of the Balance and must be regarded as the canon of the equilibrium of every thing.

The number 17 has a particular importance in the tradition of the trade guilds which acknowledge 17 journey men initiated by Alî, 17 patrons of those who founded the muslim guilds initiated by Selmân-i Fârsî, and 17 main guilds (meln, 455 s.).

To the ancient Greeks, 17 represents the number of consonants in the alphabet, with 9 silent consonants and 8 semi-vowels or semi-consonants. These numbers were also tightly linked with musical theory and the harmony of the spheres.

We previously wrote that 17 was 9+8 and 72 was 9×8; furthermore when adding the digits of these numbers, we get 8 for 17, and 9 for 72. The 9:8 ratio is endlessly recurrent in the ancient Greeks' arithmological speculations, whether in grammar, music (the 9:8 ratio being represented by the middle strings of the lyre), metric theory or cosmology.

This number may have been regarded as ill-fated in Roman Ancient Times because its figures XVII are the same as VIXI, meaning "I lived".

Today's 17's (20th century)

Computing and Video Games

HP48

On the version D of the HP48SX, 17 bugs have been found (cf William C. Wickes' file on hpcvra.CV.HP.COM).

In the 3rd issue of the French review Haute Performance, the example chosen for the challenge (page 10) is divisible by 17 (it is 2754), and the program ran for 0.102 second (divisible by 17) for this example. In the 6th issue, page 5 (rubric programmes divers, title Le recordman), it is written that an adherent has sent a 17-page letter!

On the HP48SX (in radian mode), 17 is the least positive integer n such that INV(INV(sin n)) = sin n, INV(INV(cos n)) = cos n and INV(INV(tan n)) = tan n.

Atari

In the 36th issue of the French review Atari Magazine, at the page 17 of the detachable insert, 14 file names end with 17!

In a file A_LIRE of the software Le Rédacteur 4 for the Atari, an example of hour is given (on line 438): 17h 17' 18"; in fact, since on the Atari computers the number of seconds is always even, it can be 17h 17' 17" as well. In the database AZthèque, each form contains 17 fields of free definition, and each of the fields contains 17 subrubrics.

In the assembler Assemble on the Falcon, the k-factor used by the internal conversion into packed is 17 by default (cf French user manual, p 26). There are 17 kinds of optimization (cf French user manual, p 59).

In the French software Compte-Chèque on the Atari, the date can be modified. The example given in the user manual (page 55) is July 17, 1987 (I discovered this on November 17, 1993).

On the Atari ST, just after the computer has been switched on, 17 files at the maximum can be simultaneously displayed in the desk windows, in text display.

The joypad controller of the Jaguar has 17 buttons.

The Falcon 030 operating system supports 17 countries (cf The Atari Compendium, p 3.5): USA, Germany, France, United Kingdom, Spain, Italy, Sweden, Switzerland (French), Switzerland (German), Turkey, Finland, Norway, Denmark, Saudi Arabia, Holland, Czechoslovakia, Hungary.

About the Moon Speeder game on the Falcon, in ST-Magazine 90: "You are Damon Schumberger, the world champion of gliders, and for the first time since the terrible accident of March 2117, which killed 17 of the 23 pilots of the championship and left you paralyzed for life in your chair...".

Acorn

On The RISC Disc volume 1 CD-ROM for the Acorn Risc PC, there are 17 Photo CD images.

From the help of Black Hole 2: "Mode 12 sprites should be around 34×17 pixels. Mode 20 sprites should be around 34×34". According to RISC OS style guide, large icons (for the files) must be 68 OS units high (i.e. 34 pixels in high resolution), and small icons must be 34 OS units high (i.e. 17 pixels in high resolution).

Under RISC OS, the system calls are done with the assembly instruction SWI followed by a 24-bit number. The bit 17 of this number, called bit X, is very particular: it has an influence on the error handling (it is the only bit the programmer must know the meaning).

With the VoiceMail software (answerphone system), one can record over 17 hours of messages if there are 100 MB of free disk space (cf manual, p 2).

By default, 17 files are displayed in the filer windows, in full info display.

Processors

For the processor 68030 in a Ceramic Surface Mount case, 17 pins are attributed to GND.

A square meter of silicon (chip) costs 17,000 F (cf ST-Magazine 75, p 18).

The ARM6 (the RiscPC, Newton, and 3DO processor) has 17 registers (accessible in User mode): 16 general registers (including the PC and the SP) and the status register.

C. Liem, P. Paulin, M. Cornero and A. Jerraya's article Industrial Experience Using Rule-driven Retargetable Code Generation for Multimedia Applications (8th International Symposium on System Synthesis, in Cannes, France, September 13-15, 1995) deals with a VLIW chip that has a 68 bit wide instruction. Thus this instruction is written with 17 hexadecimal digits.

For example, the denominator in Coe's now famous ratio

is

    3145727 = 3*2^20-1 = 23.99999237060547*2^17

In this case, n = 23 and f = 1-2^(-17).  The 17 consecutive high

From Constructing Minimal Broadcast Networks, N. Ossipova's analysis (D.E.A. Informatique): In the large class of minimum broadcast networks (MBN), one can find graphs that also realize a lower bound B(n) over the number of edges. Unfortunately, recognizing them is a NP-complete problem; there is no method to construct MBG for any n. The B(n) values are only known for n = 2^k and n <= 17.

Team 17's FAQ is composed of 17 questions. From this FAQ:

In early 1988, Martyn Brown founded the 17Bit Public Domain library for Atari ST and Amiga computers. The name came from the fact that the machines were using 16-bit technology and the library aimed to be "That bit better" thus the name 17Bit was formed. Team 17 was a development team formed from 17Bit contacts.

A software patent protects the software for 17 years (cf http://web.mit.edu:1962/tiserve.mit.edu/9000/24581.html).

Math

The number 17 appeared twice in the 5th French Championship of the Mathematical and Logical Games (Championnat de France des Jeux Mathématiques et Logiques): the solution to the 3rd exercise of the heats was 17; and in the 2nd exercise of the 2nd day of the finals, the 17th card was asked.

In the 9th exercise of the 7th International French Championship of the Mathematical and Logical Games (Championnat International de France des Jeux Mathématiques et Logiques), the answer was 289 (there are 17 rows of 17 cabbages).

At the finals of the 8th International French Championship of the Mathematical and Logical Games (Championnat International de France des Jeux Mathématiques et Logiques), second session, in the 2nd exercise: there are 17 animals in Belbosse zoo.

At the finals of the 9th International French Championship of the Mathematical and Logical Games (Championnat International de France des Jeux Mathématiques et Logiques):

The first issues of the French review Jouer Jeux Mathématiques costed 17 francs. In the 3rd issue (page 16), the solution to the problem Records à battre, which had been set in the 2nd issue (page 17), is given; the answer is 17. The answer to the problem Aventure en Nouvelle-France of the 6th issue is 17.

In the 11th issue of Jouer Jeux Mathématiques, there is, concerning the first question of the competition: a poplar grove has 289 poplars (17×17)... (see the rubric open problems, page 17, ...). The most chosen numbers (between 1 and 100) at the second tiebreaker are 17 and 23 (4 times). Among the 12 winners, the most chosen number is 17 (twice).

In each issue of Jouer Jeux Mathématiques, properties of a number are given: rubric la Vie des Nombres. In the 17th issue, the chosen number is 289 = 17². In the 8th issue, the chosen number is 512 and it is written: "On the circle graduated into 360 points, 512 is [...] at 3/8 round from 17, a number rich in curiosity."

At the French Mathematical Summer University in 1991, there were always 17 students. At the French Mathematical Summer University organized by the FFJM in 1992, there were 17 teachers, assistants and personalities.

His will stipulates that the eldest is to receive half his property, the second son is to receive the third of his property, and the third one is to receive the ninth of his property. On his death, how would you share out? Solution: borrow a camel, share out, and give back a camel (1/2 + 1/3 + 1/9 = 17/18).

Well-known and interesting problem: x and y are integers between 2 and 100. Stef knows S = x+y, and Pat knows P = xy, but they do not know x and y. "I can't calculate them" Pat says, "I knew" Stef says, "So I know these two numbers" Pat says, "In this case, so do I" Stef concludes. Solution: S = 17 = 13+4.

From an article from Chris Caldwell posted to the sci.math newsgroup: 17 primes of the form n!+1 are known. The corresponding values are: 1, 2, 3, 11, 27, 37, 41, 73, 77, 116, 154, 320, 340, 399, 427, 872 and 1477. There is no other for n < 4580.

Science

Pluto is the only planet out of the ecliptic plane. Its orbit is inclined of 17°. The last mission to the Moon was on Apollo 17 in 1972 (17×116). The period of revolution of Callisto, discovered in the 17th century by Galileo, around Jupiter is 17 days.

The periodical cicada has a juvenile stage of either 13 years or 17 years. It is conjectured that the reason that these insects have a juvenile stage of a prime number of years is that it makes it difficult for their predators to lock onto their life cycle and decimate them every time they emerge as adults, e.g. a predator with a life cycle of 4 years might pose problems for them if they had a juvenile stage of 16 years.

Students from E.N.S. Ulm (France) wrote a little story. The narrator's aphasia lasted 17 minutes.

In French, because it is not translatable (found in a French newsgroup):

Comment caresser une femme dans 17 départements à la fois?

Il faut d'abord trouver une femme dans la Moselle. S'assurer qu'elle est Seine, Gironde et bien en Cher. Lorsque l'on sent son Eure venue, on commence par lui caresser le Haut-Rhin puis on descend vers le Bas-Rhin. On contourne alors l'Aisne pour entrer dans la Creuse. Là, on trouve quelque chose de bien Doubs. Sans perdre le Nord, on attend que ca Vienne et si on ne se débrouille pas comme un Manche, on peut y rester jusqu'à l'Aube. En Somme, il ne s'agit Pas-de-Calais pour être un Hérault.

In a signature: "To express oneself in seventeen syllables if very diffic."

From an article posted to fr.rec.humour on February 7, 1996 (translated from French):

It's the story of a Swiss forger (yes, they exist, recently some of them even managed to forge fake coins, so fake that they aren't even accused of forgery, but only of swindle!) In short, our forger prints fake banknotes of 17. Of course everyone refuses his notes. Then he thinks about going to use them in Appenzell (For the non-initiated, Appenzell is a very beautiful place, but comes from another time; the best proof is certainly that it's no more five years since women may vote)... Let's resume... he decides to use them in Appenzell and goes to buy the newspaper in a kiosk. He pays with his note of 17 ... and the employee gives him back a coin of 15.

From an article posted to fr.rec.humour on February 11, 1996 (translated from French):

A dwarf had 17 children

(it is short but it is good)

Quotation (Willie):

My mule wouldn't walk in the mud--(sniff)--so I had to put seventeen bullets in 'im.

Quotation (Charlie Brown):

If you paid seventeen dollars for a mailbox and you only got one love letter, it would still be worth it. On the other hand, if you never ever get even one love letter, then you should get your seventeen dollars back... I'd like to speak to the manager please.

There is a French Web page devoted to Sherlock Holmes called Les Dix Sept Marches (The Seventeen Steps). The title of this page comes from A Scandal in Bohemia:

"You see, but you do not observe. The distinction is clear. For example, you have frequently seen the steps wich lead up from the hall to this room?

- Frequently.

- How often?

- Well, some hundreds of times.

- Then how many are there?

- How many? I don't know.

- Quite so! You have not observed. And yet you have seen. That is just my point. Now, I know that there are seventeen steps, because I have both seen and observed."

In a signature: "a penny for your thoughts... seventeen cents for your entire brain".

My 17's

Around 1985, my phone number was 34.85.24.00.: 3 of the 4 components are divisible by 17.

At the E.N.S. Lyon, we had a project of programmation in Scheme to give on October 21, 1993. On October 17, I finished mine, and I decided to read the one of a friend. I saw that his report had been saved on October 17, at 17:17!!

When I went to the LaBRI presentation (in Bordeaux) in February 1994, in the train, the seat 17 (written out of the compartment) had the number 15 inside (and the seat 15 had the number 15). In the hotel, I had the room 17.

On August 17, 1994, I came back by train from Lyon to Toulouse. The first train was to leave Lyon at 17:17. We had to wait for the second train for 17 minutes (the first train was to arrived in Montpellier at 20:36, and the second train was to leave Montpellier at 20:53).

During the summer holidays in 1994, I regularly connected to the E.N.S. with my modem; but there was a line problem, and I had to make several attempts, because the communication was generally cut off after 17 seconds (seen on the phone bill).

On October 14, 1994, other students from the E.N.S. came in my room, with two English girls who had been invited. One of these girls was born on the 17th, the other girl had a 17-pearl necklace. Someone showed me the place of the fridge reserved for the eggs: there were 17 locations for the eggs.

The neighbor facing Redwood, a new computer shop in Lyon, has 17 parrots.

A friend of mine, who is interested in this paper on the 17's, showed me his D.E.A. report: it ends at page 17 and the bibliography is composed of 17 references.

The first article I've posted to the comp.sys.arm newsgroup is the article 17.

At the L.I.P. seminar (at the E.N.S. Lyon) on December 14, 1994, examples of irrational numbers were chosen: sqrt(17), pi and e.

On March 3, 1995, I went to a friend's to see his NeXT. He showed me an application on learning with a neuronal network, where an animal had to learn how to balance a perch. The animal completely learned at its 666th try (it managed to balance the perch for more than 2 min 30 s); 666 is the sum of the squares of the first prime numbers up to 17. Note: the animal usually learns after 200 to 300 tries.

In 1994/95, my phone number at the E.N.S. is 72.72.82.89. All phone numbers start with 72728. For me, the last 3 digits are 289 = 17².

In 1995, I do my training period in Denmark. The French guide Le Petit Futé for Denmark has the number 17. The only French TV channel that can be received (TV5) has the number 17.

My WWW pages have been opened to the public since July 17, 1995. The HTML version of the list of properties (except the mathematical properties) appeared on November 17, 1995.

On November 13, 1995 at the E.N.S., I played for the first time to the Algebraic Whist, a Whist extension being played with a Tarot game + one card (79 cards in total), and a hat for each player. We were 6 and the game was played in 21 turns: 1 card for the first turn, ..., 10 cards for the tenth turn, a trumpless turn, then one goes downwards, the last turn (with one card) being special (cf below). Points are counted as follows: when a player fulfils his contract, he gets as many points as the number of his tricks; otherwise he loses the difference between his announced number and his actual number of tricks. Now here are the 17's. At the first turn (of my first game), the card that has been turned over to indicates the trump was the 17 magic (the Star, cf section Symbols). 6 or 7 turns before the end, I bet that I would arrive at 17. 2 turns before the end, I still was first with 16~points, and the second (Bill Allombert, who, like me, had attended the French U.M.E. organized by Danny Loeb in 1991 and 1992) had 15 points; we might still arrive both at 17. Bill announced 2 and I announced 0, but Bill didn't get 2 tricks. I didn't get a trick, so I stayed at 16. The last turn, as I said, is special: each player puts his card onto his hat without looking at it; thus each one knows the other players' cards, but not his own card. I had to talk first, and I announced 1 (it was the only way to arrive at 17), which was sensible since I knew that none of the other cards was a trump. The next one to talk (he was ranked last with -16 points) announced 1 too. Eventually I got the trick, so that I arrived first with 17 points, and the last one had -17 points.

There are 17 P.J.'s in the 1995/96 Amber campaign at the E.N.S.

In 1995, there are (at least) two new newspapers at the E.N.S.: Le Gros Rouge and L'Éphémère. On the first issue of the Gros Rouge, the date is October 17, 1995 (in fact, it was brought out much later, but they forgot to change the date). In the second issue of the Éphémère (I don't have the first issue), it is written that the deadline to send articles for the next issue is December 17.

In January 1996, at the exam of Architectures Temps Réel (Real Time Architectures) of the D.E.A. Informatique de Lyon, 3rd part: the exercise dealt with periodic tasks and one sporadic task; this task issued its request at the time t = 17.

At the course métaconnaissances of the D.E.A. Informatique de Lyon, we were given the paper of Master's degree exam of the previous year; there was an example of an integer: it was 17. The last problem at the exam was:

Let N1 be the mark you'll have for the previous questions. Let N2 be an integer in the range of 0 to 17. Your mark for this 4th problem will be:

What is N2?

At the written session of the D.E.A., I'm 17th out of 34 = 2×17. The median is divisible by 17.

I took my 1000th meal at the E.N.S. restaurant on February 17, 1996 (the 1000th meal is important, for one goes round the counter).

There are 17 seats in the L.I.P. "coffeeroom". They were changed late in 1995; before they were also 17.

For my training period of the D.E.A., I have to implement some algorithms of multiple precision multiplication. With my program, the classical algorithm in n² is better than Karatsuba's algorithm up to a size of 17 words, where a word is a 50-bit integer.

The identifier of my site http://www.ens-lyon.fr/~vlefevre/yp17_fra.html for the Webs d'Or 96 is 1207 = 17 × 71.

On June 20, 1996, at 16:45, someone wanted to phone me (but I wasn't there) and let the phone ring 17 times.

I was the 17th to sign Mirko Vidovic's Livre d'Or.

I was the 17th to sign the petition to protest against France Télécom.

On March 22, 1997, I went to a coding-party by train. I had the seet 71 in coach 17. The train for the return journey left from line 17.
