QUEUED AS 11p9_251

11+9,251 is a HCN which has just finished with ECM on Yoyo@Home. It is a SNFS job of difficulty 261, now ready for sieving.

Code:
n: 5507055008503847175427511836444905477655887936904443750226051734874957287516406651481980830600296706186305964116385320439184175993965217750449712142253210690764509266067631759794594378142148043497899052874021952102052057

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

Code:
MQ       Norm_yield      Speed (sec/rel)
40          1934              0.359
70          1706              0.433
100         1518              0.470
150         1321              0.550
200         1129              0.674
250         1111              0.637
Suggesting a sieving range for Q of 36-215M to generate 260M raw relations.
