Just post them in this thread (with code tags around them, so the page doesn't get screwed up) and submit them in the factordb.com ;).

I have been reporting just the BL time, not the entire -nc time.
What does everyone prefer?

I've always been reporting the BL time

What does everyone prefer?[/QUOTE]Personally I'd prefer to learn the number of which this is the factorization. No real trouble for me to discover it was GW_3_505 but it was an additional step nonetheless.

Thanks for your work. Much appreciated!

Arg! Could a mod update the title of my post, please.

Adding the trailing question threw off my brain wave patterns. I'm glad I don't solve these numbers by hand. I would never get the right answer. :smile:

Great thanks.

[OT] what version of MSieve would you recommend using? I am using 153_SVN967_64bit can you please provide download link for windows should I need a later version. I am doing 61111_221 Thanks[/OT]

Linear algebra for C261_139_75 started
 

Should have results next Friday morning (25 September); it's a 21.7M matrix, msieve says
[code]
Sun Sep 13 02:36:37 2015 memory use: 8526.2 MB
[/code]
but the actual vsize is about 12GB; it looks as if the matrix-build step probably would have fit on an otherwise-idle 16GB machine.

The blue block on the attached graph says this number took about 14 days for the sieving (of which six days full-time and the rest picking off stragglers - next 260-digit SNFS should aim for 450M relations from the start), for about 12 days of linear algebra on i7/4930K.
