Could anybody please help me find an up-to-date ECM effort on the repunit cofactor C204 / R1740M / 10,870+ http://factordb.com/index.php?id=1100000000032341587 ?
Is it potentially ready for GNFS?

Hi Max,

ecm runs at YOYO - B1= 850e6 - target: 70000c

I looked under RepUnit in https://www.rechenkraft.net/yoyo/y_status_ecm.php, the number is not listed there.
Could you please post a link where I can see how many curves are finished?

kurtb · 2019-07-25, 19:34

Max

the R1740M-ecm-instruction will be uploaded to the server in about 5 hours;

Max,

Are you able to spin up this poly for a C153 (aliquot sequence 434040, i3097)?

CADO can't do it, I'll try msieve a bit later.

Max0526 · 2019-07-29, 11:50

@richs
I can't spin it up, sorry.

Need a poly for C179_M13_k85 from the kosta subproject.

Code:

62933469061335540106807936298327874448638377986945863197760785525372837825198370470531794398015301457415136423514956791972024770931875426233642393792271758240069039032418524326531

I’m starting on the range 0-2M using msieve-GPU. Any help would be greatly appreciated!
