Congrats to all involved (which doesn't include me) for factoring the smallest remaining Mersenne number!

I've added the new factors to Syd's factoring DB. c259 = p7*p50*p62*p141
Going to take a whack at M863 next?
How does this factor get added to PrimeNet v5 and properly credited? http://www.mersenne.org/report_facto...B1=Get+Factors

We're currently attacking M877, since I like alternating GNFS and SNFS runs; come to the neighbouring thread and join us! One million Q takes about eight days on one core of a 2.4GHz Core2 running 64-bit Linux, probably about twice that if you're using Windows; 133 million Qs remain unclaimed.
