How small must a quartic be? I've got a P58^5-1 that has had a t50, but it sounds like SNFS 231 is too big.

Sorry, bad wording on my part, I meant "done" in the sense of the deal is done, not that I'd factored it. I should have said "Taken". ETA about 3 days from now.

Tell me the value of p and I'll put it up on the 15e queue. Last fiddled with by fivemack on 2015-02-26 at 18:19

No idea when it will get done - I think the queue is long enough that even the Challenge won't burn through it, so it may take months before your number reaches the top of the queue and gets sieved in a few days.

I realized that this numbers has ECM to 2/9 the SNFS size, but it should have more than this to compensate for the Quartic penalty. I figured a few months would give me ample time to quietly get the extra ECM and pull the number if a factor was found. But that plan has been foiled by the advancement of all queued numbers to sieving status in preparation for the upcoming Challenge. Please accept my apology and de-queue the number, replacing it with better prepared numbers.
