Once upon a time, when I was training to be a mathematician, a group of

us bright young students taking number theory discovered the names of

the smaller prime numbers.

2: The Odd Prime --

It's the only even prime, therefore is odd. QED.

3: The True Prime --

Lewis Carroll: "If I tell you 3 times, it's true."

31: The Arbitrary Prime --

Determined by unanimous unvote. We needed an arbitrary prime

in case the prof asked for one, and so had an election. 91

received the most votes (well, it *looks* prime) and 3+4i the

next most. However, 31 was the only candidate to receive none

at all.

Since the composite numbers are formed from primes, their qualities are

derived from those primes. So, for instance, the number 6 is "odd but

true", while the powers of 2 are all extremely odd numbers.

Mathematician's Proof

3 is prime. 5 is prime. 7 is prime. By induction, all odd numbers are prime.... - pseudoprime n.
A backgammon prime (six consecutive
occupied points) with one point missing.

This term is an esoteric pun derived from number theory... - Mathematician: 2 is prime, 3 is prime, 5 is prime,
7 is prime, 11 is prime.

The first student to try to do this was a math student.... - HAKMEM /hak'mem/ n.

A legendary collection of neat mathematical and programming hacks contributed by many people at MIT and elsewhere.... - one-liner wars n.
A game popular among hackers who code in
the language APL (see write-only language and line noi
and/or useful routine in one line of operators chosen from APL's
exceedingly hairy primitive set.

A similar amusement was practiced among TECO hackers and is now popular among Perl aficionados.... - 3 is prime, 5 is prime, 7 is prime, 9 is experimental error, 11 is prime...
