So the only one with less than 170 digits is[QUOTE=XYYXF;404536][b]C162_144_37[/b], 7600 curves at B1=43M, perhaps needs some curves at B1=110M

I ran some polynomial selection on C162_144_37 and am content that it's an SNFS-number

All the numbers mentioned are factored :-)

Hi,

Where on the project webpage can be seen a list SNFS composites ready to be added to NFS@Home sieve?

Kind regards,

Carlos

I don't think that's quite what he's asking for; he would like SNFS numbers where the ECM has been completed, which appear on this thread but immediately get snapped up.

So I think the suggestion is to go to [url]http://mersenneforum.org/showpost.php?p=432408&postcount=1[/url] and run the prescribed ECM, and then factor the numbers.

It might be wise to wait until I've got my Bayesian how-much-ECM-to-do tool working properly; it depends on the relative values you place on avoiding ECM misses and avoiding having an empty queue.

[B]C284_135_127[/B] survived 20k+ curves at B1=300M. Maybe that's enough?

XYYXF 2016-11-03 08:53

C242_129_101

is ready for SNFS :)
