QUEUED AS C175_3408_1704

AS 3408:i1704 is a GNFS 175 from a series last worked by RyanP, who gave it plenty of ECM before stopping his efforts (19,000 curves @B1=260M).

Code:

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

Code:
MQ       Norm_yield      Speed (sec/rel)
40          3369             0.239
70          3422             0.275
100         3136             0.329
140         2867             0.330
Suggesting a sieving range for Q of 40-120M to generate 260M raw relations.
