I have decided to release this one as the yafu generated polynomials had low yields. I suspect that it may be a better GNFS target and I am looking for SNFS targets.

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.

Code:

Using B1=110000000, B2=776278396540, polynomial Dickson(30), sigma=2:16051517285729009536

p56 = 11001408445322442725084040681118498707463418219503651061
c177 = 991228703356654215320094822246590842143099866343312764192983407857543191606905831730899101570202293619679025230570017723592113805005106645373624444062802119075689704001581124479

I have decided to carry on sieving the 177 digit cofactor.
