 2004-09-16, 08:03 #2 biwema     Mar 2004 38110 Posts I assume you mean "finding at least one factor of MM127 and prove the number composite". Comlpletely factoring would be rather difficult...

How far are we from that? I think that we will find a factor for M1061 or find M42 first.

 Countdown to proving M(13466917) is the 39th Mersenne Prime: 27,655
What really bothers me is "Countdown to testing all exponents below M(13466917) once: 3" - this hasn't changed more a long time. Hurry up, you 3!!!

It may be helpful to keep in mind that if the assignments being handled by slow computers were instead handled by fast computers, the assignments that would formerly be assigned to those fast computers would go undone as long as the fast computers were diverted to the "slower" assignments -- a net loss for GIMPS because that would delay progress toward future milestones. IOW, it's better for GIMPS to proceed at an overall speed of 101 than at a speed of 100. :-)

 2004-10-15, 21:37 #10 Terrence Law   May 2004 2·37 Posts Change the sign or command to MM127 proven prime. I'm sure that it will be the VERY last of the four that the milestones will occur in order.
 2004-10-15, 21:39 #11 Terrence Law   May 2004 10010102 Posts Factoring Depth. It seems very unlikely that someone would successfully find a factor for MM127.
