I can do GNFS on the C153 if it has received enough ECM.

yoyo@home has 7800 @ 43e6 in the input queue but it hasn't gone active yet.

ricky · 2018-12-09, 21:25

I am doing it, it will finish quite soon, so it's not necessary that yoyo@home does it.

The C153 factors as

Code:

p74 factor: 19928638114143557639348319790409168695610012346109977780982024608631375087
p79 factor: 7798641889897770108922816559374634253586927781674138840644647051053991265389963

I have added some more term to the sequence (and currently doing ECM on a C194).

ricky · 2018-12-27, 12:47

I've ECMed the C194 with 14716 curves at B1=110M (yafu's default for t=55), without luck. I'm stopping working on it.

yoyo · 2018-12-27, 13:40

I'll run the t=60.

yoyo · 2018-12-28, 07:26

A p57 found. Now it is a C165.

Nice hit!

Unfortunately, the D2 is difficult to lose, especially at this size. On the bright side, if it does not get a 3, then it is steady (i.e. it doesn't grow much), and 5 is not sticky. But unless we double the seven, there is no much hope...

Maybe we could find a "better" sequence to tickle? :wonder:

ricky · 2018-12-30, 11:16

Great! I am doing the C165.

ricky · 2019-01-13, 10:03

It's now a C167. I've ECMed it with 7553 curves at B1=43M without luck and I'm dropping it.

yoyo · 2019-01-13, 10:25

I'll run all B1=110M curves.
