unreserving 165546 at i=1078, sz. 125, 2³*3 (without a 5, is this a driver?)

cofactor c112 had just a little ECM (full t30 + a fistfull @1e6)

Releasing 89190
 
89190 is at 136 digits, 2^2*7 driver, term 1097 has a C131 which has not split after 7000 curves at B1=1e5. I'd like to stop work on this sequence.

7000@1e5? Is there a reason why you don't do (only) ~500@1e5, then ~1000@1e6 and then continue with 3e6 and 11e6 (or 1e7)?

I think it's actually 1000@1e5 then 2000@3e5; my driver program counts equivalent-curves-at-1e4. I normally let the driver program finish, then run curves at 3e7 for a while, then GNFS.

Reserving 89610 for Clifford. He says he captured the downdriver at 134 digits....

schickel 2011-02-25 08:12

I might have to go to a 4-core job on one of the project 400 sequences (a c126), so I'll take 733776 for a spin on my slower machine....

reserving 166768 (bcaffin added 3601 terms in the [URL="http://www.mersenneforum.org/showpost.php?p=253754&postcount=76"]subproject #9 thread[/URL].)

It's time to free some tough sequences :hello:

Releasing 151140, Got down to 20 digits at one point, but now is up to 112, with driver 2*3^3

Releasing 61422, 120 Digits with driver 2^2*3^3*7

-------

Sadly the downdriver mentioned for 827880 above lasted only for 7 indices. It picked up 2^2 - fortunately without a 7
