kaminix: I know of only one "easy" way to find a probable prime, but it's not something I could do without program assistance (2^76492 mod 76493 anyone?). I looked up sieves as an alternative, but they seem pretty useless too without help, unless there is some kind of sieve method specifically for larger numbers that I haven't come across yet.


59711 is still up there if anyone's willing to tackle it
