We've still got that 2^5 * 3 :rant:

And we've reached 160 digits :rant:

I think we've done enough ECM from what's in the database; does anyone want to crack the C134 themselves or shall we make it a team GNFS?

No reply. I guess it will be a team sieve, then.

Hi all,

I am pleased to announce that the nplb-gb1.no-ip.org FTP server is back online again. It should be all ready for the next team sieve. :smile:

Would you like to do the poly search for the c134?

The best poly from Msieve till now for the c134

No thanks--I'm afraid my resources are quite tied up at the moment. Right now, going through the available subproject sequences one at a time is all I can handle.

The best I got from pol51 was a 4.37. I think this one is good enough.

I searched 770-775K with msieve and got a 3.734e-11.

def-nm-params.txt says a "good" poly for c134 is 3.48e-11. So a 4.814e-11 poly must be great. We should start sieving with it.

Suggest these parameters? I did not optimize them:

It's only a C134, so sieving time will be so small (compared to a C157) that I think we should just take the best: anyone want to test the parameters for the 4.91?

FYI: The FTP server will be available, as before, for this team sieve. I've got the directory "c134-relations" all set.
