I believe the idea of trying to skip P-1 factoring was talked about within the last 3 or 4 months. Apparently there are people who would just prefer to get credit for doing LL work than to find factors. This is why I like that you loose credit for a LL-test if someone else finds a

If we could indeed track these to a single user, I've got about 25-30 AMD 1.2 GHz processors that I could throw at the situation for a short time, just to quickly re-trial factor these and put our minds to rest. Aaron - Original Message - However if it could be established that all the
