Help needed to factor Bernoulli(200)! I hope Free-DC team is interested getting into Math History.

Barry Mazur and William Stein wish to include the factors of the numerator of the 200th Bernoulli number in their upcoming book, and you can help! This is a large GNFS factorization, but NFS@Home has the ability to sieve it in 2-3 months. Therefore, I am placing 2,1019- on hold for a bit. If you have the memory for it please use the lasievef application help factor B200, and let's complete it as quickly as possible!

10,305+ is now factored into 75-digit and 135-digit prime numbers. The sieving of 2,1061- is nearly complete. (Really this time!) The sieving of B200 is going well, and once the sieving of 2,1061- is done the V5 applications will also be used to sieve B200. Let's get B200 done as quickly as possible!

A 64-bit Mac OS X app has been released. It uses less memory and is much faster than the older 32-bit app for Mac
Greg's reply on mersenneforum:
I put the V5 apps on the largest q's and it's working down. The older apps are on the smallest q's working up. They will meet somewhere in the middle.
Currently, there are 100k workunits not yet released and ~110k released but unsent or in process, so we are about halfway there. We are currently doing ~14k workunits each day, so giving a few days for the long tail, sieving should be done in about 3 weeks.
