The best poly for 7,373- so far.
I let the polyselection continue for a while.

Code:

I'll also look for a better poly for 11,671M.

Guys, please check here the current list of integers fed or to be fed to the grid.

https://escatter11.fullerton.edu/nfs/numbers.html

Right now we are completing sieving of 6,460+, rest below until 2,1079+ is done for the moment.

That is considerably better! It reduced the sieving limit from 900M to 560M, and has been submitted to the grid. I will be submitting 11,671M to the grid tomorrow and 3,703+ likely on Friday.

Gimarel · 2016-10-12, 08:38

I hope that it's not to late. Here's a better poly for 11,671M

Two better polys for 3,703+.

After a good deal of ECM, now hoping to find a poly for C186_145_72 from the xyyx project.

Amorphia found a decent polynomial in a target range of 3.66e-014 to 4.21e-014.

Can anyone help find a better poly? Thank you in advance.

It wasn't. We used yours. Also, thanks for the others!

Bump. Can anyone find a better polynomial? I don't have a GPU rig. Thanks.

That's a pretty good poly score for a composite this size. I think you can just run with that one!
