lasieved and lasievee queue
 
Who collects the results for Lucus/Fibonacci numbers? I'd like to email them in case (s)he isn't following this thread.

BTW, the lasieve[B]E[/B] queue is almost empty. The last number in the queue (L1926) has already 59M relations of the ~250M NFS@home usually does for numbers that size. So I guestimate the buffer will be empty in about a week. Are there any candidates ready for NFS with appropriate (S/G)NFS difficulty???

Another heads-up:
GC_3_512 is queued [B]TWICE [/B]in the lasieved queue.
GC_7_282 still needs to be re-sieved with correct poly/ini

[QUOTE=VictordeHolland;388490]So I guestimate the buffer will be empty in about a week. Are there any candidates ready for NFS with appropriate (S/G)NFS difficulty???[/QUOTE]How big is that? I may be able to find one or two but most of the ECM effort so far has been dedicated to smaller numbers.

I don't know the precise requirements, but the last ones were in the range SNFS(260-270) and GNFS(169-179).

Cofactor of [URL="http://factordb.com/index.php?query=I%281345%29%2FI%28269%29%2F5"]F1345[/URL] could be a nice target.
The polynomial is a quartic which should be propped with uneven fb lims - the patterns for large quartics are easily found in older quartic projects. Then, maybe, F1405 and F1415 - using the same poly. All three have no known factors and are well-ECMd.


[COLOR=DarkGreen]EDIT: P.S. Because there was no interest, I'll run F1345 myself.[/COLOR]

Yup, I had noticed your previous post and I sent an e-mail to Greg about that, indicating that I'd kill one of the two entries :smile:
But I haven't done so yet.

IIRC, I need to queue at least one non-GCW number: a Home Primes C158 for Dubslow.

(Probably. I know I had one.)

It sure aint me, guv.
