I found the aliquot sequences interesting mathematically, and was following the links from other aliquot pages and found one to the forum.

I pasted the start of a run below so you could see the set up. It has the ggnfs line (and describes a second issue).


I have not successfully run ggnfs yet, which is why I think my settings are likely wrong. Is there a command I can give that will call ggnfs on a value known to work? I could test that and see what the result is.

These are the files I downloaded:
aliqueit107.zip
ecm622_win32_intel.zip
ggnfs-svn340-win32-p4.zip (do I want the svn360 version?)
msieve141_win32.zip
yafu-1.10-win32bin.zip

I am running vista, my system type is 32-bit Operating System. and the processor is:
Intel(R) Core(TM)2 Duo CPU E4600 @ 2.40GHz 2.40 GHz
2 GB of ram.

I also got another problem with yafu (see bottom)

^C9: running qs (yafu)...

The screen spammed the warning alternating the 'running qs (yafu)' message seemingly forever.
