The firepower that has been brought to bear with the GPU's is very significant. So, I hope the results (and factors) should flow in rapidly.

Ended my both MM89 and Fxx N=90 ranges. The factor still managed to stay hidden, but my feeling is that he is now cornered and sooner or later someone will put the paw on it..

Not sure if I missed yall catching this, but
no factor for k*2^43+1
should be no factor for k*2^2^43+1, right?

no factor for k*2^43+1 means there is no factor of the form k*2^43+1 dividing a Fermat number (F(45), F(46), ...)

But you have to use a version higher than 0.20 http://www.mersenneforum.org/showpos...5&postcount=95

Sadly, my 1+% shot at cracking MM127 fell short.

Code:
