Ryan got another big hit, finding a p68 in C238_149_79, followed by GNFS to crack the C172 cofactor (p88 * p83).

Both this factor and the p70 he found in 131^128+128^131 (see prior post) are both...

The commonly used ratio of GNFS/SNFS is 0.68 to 0.69. This ratio doesn’t hold true here for the case of SNFS 210 ~ GNFS 155 but those values are on the low side.

Yes. I do the same thing at times: SNFS = log(13^282+1) = 314 but as you say it ignores the algebraic factors.

Phi() is another tool for generating accurate SNFS polys.
