[QUOTE=jyb;524819][QUOTE=fivemack;524800]

Hmm, no I didn't try that and I obviously should have. I did just now, and it sieves a little bit better with your suggested change (like maybe about 7-8% better). This number has been queued, but it hasn't yet had any work units handed out. It would be possible to remove it and submit the change, if we can get Greg to cancel the work units before anything is handed out. It's not clear to me whether that would be considered worthwhile, given the modest improvement, though other things being equal I would of course prefer to see resources used as efficiently as is practical. I guess I'll have to leave that decision to those who are managing the queue.[/QUOTE]

Sorry I didn’t read this discussion until now. Seems too late to cancel the job at this point.

Please, more non-Fibonacci 15e jobs!
 

I feel I'm rather hogging the 15e queue with Fibonacci numbers; it would cheer me up if some OPN or aliquot candidates came along ... I've seen a 180-digit GNFS go past on 14e, which I'm not sure wouldn't have been better on 15e

Thanks to the above comments by [B]fivemack[/B] I am seeing remarkable results with degree halving p^17-1 using an octic. I have a handful I will be sending this way, and a few others...
