QUEUED AS 8p5_335

8+5_335 is an HCN quartic with a SNFS difficulty of 242. It has undergone 22000 curves of ECM @B1=260M.

This job fits in the 15e siever as a 33/32 hybrid job:

Code:
n: 154638272499362641606228283579656901102089373552494768984575062529997233820535651473204362623824358987210848708149145544010671579239535371075454996454471258013711363665787732352099580940921

Test sieving on the -r side with Q in blocks of 1000:

Code:
MQ        Norm_yield       Speed (sec/rel)
35           2126               0.367
65           2491               0.416
100          2720               0.413
150          2694               0.409
200          2580               0.402
300          2409               0.404

Suggesting a sieving Q-range of 35-290M to produce 650M raw relations.
