If it was easy it wouldn't be fun, would it?

Oh here it is:

And may I add that, scientifically speaking, it is an equally important result not finding factors as it is finding them.

YOOOHOO!
11925*2^80011+1 is a Factor of GF(80004,12)!!!!

nevermind, already ion the top 5000 database

Mr.(hustensaft) Happy, I suppose...

Even Mersenne numbers with regular prime exponents in the 10M area take a year or more on a GTX580 when you get above the 80 or so bit range for trial factoring. Is there anything like mmff that could do partial bit ranges so the work could be spread across multiple GPUs? It is discouraging to see ETA 302 days.

I'm sure Oliver "The Judger" is thinking about it...
