Wow, that’s an outstanding poly sir! Better than the record deg 6 for a C211. Congratulations!

23_193m1

Well, based on results to date, adding 20M+ Q should get this job to 270M uniques. I’ll keep bumping Q if yield degrades along the way but I suspect this job will reach that goal by the weekend.

I tried both sides. I usually look at 2/2, 3/2 and 2/3 LPs and test sieve each case on the -r and -a sides. Wasn’t a lot of difference but the rational side won out.

Odd Job

C235_131_106 from the XYYXF project. A strange one to be sure.

I test sieved both the deg 5 and deg 6 SNFS polys. Neither sieves all that efficiently, I assume due to the awkward coefficients. But...
