Oh yeah, one digits which matters. Anyway now i'm on track with 11e7 as stated above.

I'm going to polyselect this C177 (i12546) and submit to the 14e queue.

Sorry, I'm already working on this c177 -- it's in LA and should be done sometime tomorrow. (Should I have reserved the sequence somewhere?)

Nice timing, sir. After two months of no posts, a reservation doesn't seem necessary; if you did report your work plans, please use this thread.

Thanks for the help!

Correction, CADO-NFS has only completed the first stage of LA (krylov). Looks like we'll have the factors on Wednesday.

This series seems to have stalled at i12553 (C169). Anyone still working it?

I'm still on it. I'll post a note if/when I release it.

Finally, with 12562 known terms, this sequence has become the longest sequence below 1e6 for the moment.

However it will be impossible to beat 2005020 without a downdriver.

Default index 12566

Bad news: the c205 at index 12566 (1905316801...) has thus far failed to yield to ECM.

I've run 83K curves at B1=29e8, but no hits. May continue on at B1=76e8 after.

Could this be a good GNFS target for the forum? I may not have the time/resources to devote to it.

Yes, yes it could. We'd appreciate it if you could aim a couple of CADO clients at the forum server if we do take it on; I'd run it on I=15, so each client would be ~3GB memory. Sieve time would be on the order of 75 [hyper]thread-years.

Those who donate client-cycles may prefer to tackle the c204 GNFS cunningham target first, or either of these might just get sent to Greg's 16e queue at NFS@home.
