[QUOTE=amphoria;398240]Reserving C233_122_83 for factoring by SNFS.

I chose this one initially because it would be in the SNFS record table. However, I ran some t55 curves first and found a 56 digit factor after only 1292 curves.

I have decided to carry on sieving the 177 digit cofactor.[/QUOTE]

The factors are as follows:

About seven CPU-days for polynomial search, about 2200 CPU-hours K10@1900MHz for sieving (146M relations, 31-bit large primes, 14e siever), about one day on four cores i7/4790K for linear algebra (6.8M matrix). Log attached.

BTW this job took ~10 days to sieve, plus a few more for LA. Call it 2 weeks overall.
