A backgammon prime (six consecutive

occupied points) with one point missing. This term is an esoteric

pun derived from number theory: a number that passes a certain kind

of "primality test" may be called a `pseudoprime' (all primes

pass any such test, but so do some composite numbers), and any

number that passes several is, in some sense, almost certainly

prime. The hacker backgammon usage stems from the idea that a

pseudoprime is almost as good as a prime: it will do the same job

unless you are unlucky.

- pseudoprime: n. A backgammon prime (six consecutive occupied
points) with one point missing.

This term is an esoteric pun derived from a mathematical method that, rather than determining precisely whether a number is prime (has no divisors), uses a statistical technique to decide whether the number is `probably' prime.... - Once upon a time, when I was training to be a mathematician, a group of

the smaller prime numbers.
