I tried using the "obvious" degree-6 poly: Code: n: 6057169040...87 m: 732541^8 type: snfs deg: 6 c6: 1 c0: -732541 Even using 3LP, or trying to sieve on both the algebraic and rational sides, I'm getting really poor yields. Most of the time, gnfs-lasieve4I16e (which is really lasieve5 that supports higher q values) spits out a bunch of spairs.out.* files that are empty. Any ideas what I might be doing wrong? Is there a better polynomial I can use for this job?
