I'm almost done with p40 on the c139. Found a p52. Next step has a c131.

Finished p40 for the c157. Found a p47, a c110 remains. I'll sieve it.[/QUOTE]

[QUOTE=akruppa;280124]The c110 is done but by the time I finished, someone else already checked the factors into factordb.[/QUOTE]

[QUOTE=akruppa;280134]I'm almost done with p40 on the c139. Found a p52. Next step has a c131.[/QUOTE]Lucky hits on those. I was not looking forward to another c15x GNFS job. Thanks for all the ECM and GNFS work on this!

Looks like we might get just such a GNFS job. Did 4000@44M, no factor yet. EDIT: on the current c154.

[QUOTE=akruppa;280183]Looks like we might get just such a GNFS job. Did 1600@44M, no factor yet. EDIT: on the current c154.[/QUOTE]I'll run some ECM until we decide different....

I've completed a t50 so far. Nothing yet.

Add:

1200@3e6
1300@43e6

Did about 3500@110M. Looks like a GNFS job.
