    Seriously. I'm not a math major, etc. But I'm curious, is this of value? Other than of course as a curiosity.

    Actually, a twin prime is a pair of numbers n + 1 and n - 1 such that both are prime. For example, 41 and 43 are twin primes. Incidentally, if n is greater than 4, then n is always a multiple of 6; this is fairly easy to prove to yourself.

    'Course this will all be sorted out when computers can vote.
