[QUOTE=Max0526;449845]A better GNFS poly for c157. Found by CADO-NFS.[/QUOTE]Thanks, but I have since switched to the degree 6 poly for SNFS (with corrected skew). It seems to be much faster, and I think that SNFS difficulty 190 should run faster than GNFS 157.

The next group of P^11-1 includes:

P20^11-1 ~SNFS-195
[CODE]46656693519791045503^11-1
14328679365267973669^11-1
70034079084533288401^11-1
34874936178525512161^11-1[/CODE]

Nearly finished the last of those p19^11-1 numbers, so I'll reserve these two now:
70034079084533288401^11-1
34874936178525512161^11-1

9224843685451579741^11-1 had a fairly even split, p75 * p76. I'm keeping my eye out for some brilliant numbers.

I've nearly finished the last two, so I'll reserve these 13's:

1146504157422163^13-1

90739349695786069^13-1
47092133137764749^13-1
13319523584541029^13-1
10113283283692423^13-1

My first factors of the year :smile:
1146504157422163^13-1 = <some junk> * p52 * p110

I'd like to reserve the last of the 11's now:
46656693519791045503^11-1
14328679365267973669^11-1

I'm afraid I've lost access to one of my PCs temporarily, so 90739349695786069^13-1 may very well already be factored, but it will take me some time to get to it and retrieve the factors. It will likely be at least a week unless I manage it through other means.

Well I managed to get access to my PC, and factors for 90739349695786069^13-1 are on FDB now.

As far as I know, the following numbers still need to be factorised and are without reservation.

P46^5 - 1, SNFS 180 - 184

I'll reserve the last one of each block:
9936971000787962387393134426179179209782538661^5-1
6924478858931407658578569945691^7-1

Since no-one else has expressed an interest, I'll reserve all of those P46^5 - 1 and P31^7 - 1 numbers from my last post.

The next groups. These will take several days (on a Core-i5).

I usually grab mine from the next (un-posted) groups so as to not post, reserve and specify done. :smile:

Next group of 5 & 7s.
