I tried to send an e-mail to Paul, met with a 550 error pointing to a blacklist, for the IP address of one of Yahoo!'s e-mail servers... Lots of e-mail woes on Yahoo! lately :sad:

Do we really mean to be using 30-bit large primes for numbers of SNFS difficulty 250?

We're getting yields of less than 0.3 relations per Q, and having to use formidable numbers of Q to get to fairly small relation counts - all previous numbers of difficulty 245 and over were done with 31-bit large primes.

Poorly written scripts gone awry. Fixed for the upcoming numbers. Thanks!

Slightly OT: I received no e-mail notification from your ECMNET server.

Ralf Recker,

The automatic notification email is not working therefore Paul is sending manual emails.

Was GW_7_270 done with SVN 967? This has what I think is a fix for the large dataset bug. Does the filtering at least work with your other number?
