 ...an extraordinary fact - probably known to half of you, but nevertheless I thought I'd share it. It's not an alogorithm, but never mind! The square of any prime number >= 5 can be expressed as 1 + a multiple of 24 or `If p is prime, then p ^ 2 = 1 + 24 * n, for some n` Don't know about you, but I think that's quite amazing. Why is it true at all, and given that it is, where does 24 come from?! (Pity it's not 42 really!)  When I ask "where does 24 come from?" I am not asking for a mathermatical proof - I can look that up myself. It's more just a metaphysical musing...) modified on Thursday, November 4, 2010 6:37 AM
