I can run GNFS on this number, if it is available.

Preferably another 2*t50 or t52 worth of curves run on this number before GNFS, but it is still available and has been assigned to you.

if you want I can upload nfs.dat.p and two other files after first nfs stage

When you say "first NFS stage", do you mean poly select?
If so, just post the best poly score here, and Ed can request it if CADO happens to not produce a better poly.
For users not named Gimarel, CADO nearly always yields better polys (Gimarel has modified msieve to search different coefficient patterns, and gets very good results).

I ran another full t50 on it overnight. I'll set it busy in GNFS today.

Thanks - I'll take a look, but I'll probably just run my CADO-NFS/Msieve script on it from the start.

The coefficient selection is only a small part. I use msieve-GPU for stage1 but CADOs sizeopt and then again msieve for the rootsieve, because it's much faster.
I modified msieve to disable the randomisation in stage1 and to use different ranges for "other". I think "other" is the same as tasks.polyselect.P in CADO.

(7,-8) c179 is done.

Done, which means (13, 5) is Fully Factored in the db.

If you like, you can book me for the c171 on line 205 (11, -5).

Does anyone know where the Max0526 went?

[EdH]

I ran some more ECM (t45) on the three composites for line 124 (9, -8) with some success (db updated):

c234 = p43 * c192

c266 = p45 * c222

The c277 survived t45. I will run all three through t50. . .
