Wow!! I doubt this can bested without a LOT more searching, but I note that the range 2-3M remains unsearched. I will take it this weekend unless ugly2dog has already started sieving.

C190 poly needed
 

C190_144_125 is one of the few remaining GNFS jobs on the XYYXF project.

TYIA for any assistance. Taking 1-2M.

I'll start with 4M in a bit.

C177 poly
 

Greetings,

Any help that you folks can provide in finding a poly for the C177 of of Aliquot sequence 829332 i3673 would be greatly appreciated. The composite has been ecm'ed to more than a t60.

[CODE]639111216358462045637168830728405128749985350094829375210689250206054960606354216550069158398935019911265433918994329538741608563810754728407214426139578313402397468065625568789[/CODE]

I am running a CPU search on this number on coefficients up to 10,000 using msieve through YAFU, and my intention is to use NFS@Home for sieving once a suitable poly is found.

Thanks very much!

C177
 

I will help once a stopping point is reached with my C190 search in a couple of days. A t60+ level for ECM seems a bit excessive for a GNFS 177 but no doubt it is ready for NFS methods now.

Taking 0-2M for the search space.

Thanks, Sean. I was hoping to hit the lottery with a t60+!

Best found for 1-2M, pretty poor.
