Do we need to run more ECM (5000 curves @B1=26e7) prior to starting GNFS?
Could you try another test-sieve with these parameters but 32-bit LP? Even if NFS@home will run it as 31, I'd like to know how much time 32 would save.

A t55 should be plenty of ECM for this number. I'm still running the C195 from the poly request thread, so I won't be able to improve this poly for another week or so.

Let's strew some 110M curves on C177_132_91 and C178_131_81. Once they survive, test sieving will clear up their status (GNFS/SNFS).
Code:
// C178_131_81

Bump. I can help with these in a couple of weeks but a group ECM effort would speed things up.

I'll do the 18k curves on C173_139_59.

I will start towards a full t55 on C177_132_91. It will take awhile.

Fully factored by ECM

Code:
p60 = 142605715251108746997064499457693518817992625513392698520987

B1=11e7
B2=gmp-ecm default
Sigma=2405137795

Reserving the following for ECM to t55:

C178_133_71
C187_142_59
C173_145_56

Thanks.

C173_139_59 withstood 18k+ curves at 110M.

C178_131_81 and C178_133_71 both survived 18000 curves @B1=11e7 with no factors found.

C173_145_56 survived 12000 curves @B1=11e7, now Fivemack is factoring it. Please transfer the reservation to him.

C187_142_59 is still under ECM towards t55. Estimate ~2 weeks to finish it.

Thank you.
