[QUOTE=swellman;487074]At 403M relations, C209_701xx141_5 seems low for a 32-bit job. Can some additional sieving be run on it?[/QUOTE]

Bump. Message was getting lost a few pages back.

Thank you.

[QUOTE=richs;486905]Also reserving C211_112xx307_13[/QUOTE]

Bump. Noting that I've started post-processing this number so no one else does it.
