Suggesting sieve range is 30M-230M, this should produce ~470M raw relations.

QUEUED AS 11m9_251

11-9,251 is a HCN just finished with ECM. It is a straightforward sextic of SNFS difficulty 261 but must be run on 15e. (A previous HCN job 11+9,251 of the same difficulty just fit into 15e_small.)

Also note that 3 LP on the rational side yielded a bit less than the algebraic side, FWIW.
