[QUOTE=swellman;498164]Which siever do you intend for this job? I think it's meant to be 15e/31 but it's not clear to me.[/QUOTE]
Oh dang it! Sorry, I meant it to be 14e/31. The yield is a little low, but it would ultimately require about the same or more total special-q at 32 bits, and 31 should give us faster post-processing. |
No worries, just wasn’t sure your intent. The job has been submitted to the 14e queue.
