QUEUED AS C173_141_103

C173_141_103 is a stub from the XYYXF project remaining after Ryan ran a swath of ECM. It is a straightforward GNFS job on 15e_small.

Code:

Results from test sieving on the -a side with Q in blocks of 1000:

Code:
MQ       Norm_yield      Speed (sec/rel)
40          3536              0.241
60          3691              0.242

120         3245              0.340
Suggesting a sieving range for Q of 40-115M to generate 265M raw relations.
