QUEUED AS 8m5_289

8-5,289 is another HCN currently finishing ECM courtesy of Yoyo@Home. It is SNFS difficulty 261 and is ready for sieving.

Code:
n: 36860066201888512290940086443141501667418852463621850457460187197232158243824348473033724380872791936275622703788081798388348161214255491322846973107383191607807366614269629612852353409309005651396853345000070868081990769485029162193001

Test sieving results on the rational side with Q in blocks of 1000:

Code:
MQ       Norm_yield       Speed (sec/rel)
40          2165               0.284
70          1955               0.300
100         1870               0.333
150         1678               0.375
200         1524               0.498
Suggesting a sieving range for Q of 38-180M to generate 260M relations.
