Here's a reply from Paul Zimmermann:

We are sieving 21 164+ c131, and the factors
should come out this week-end or early next week.

Then we'll need a new NFS candidate. 38 131- c131 is reserved for CWI.
Is 73 125- c131 still available?

Paul

Looks like these are/were the smallest gnfs? -Bruce

Reserving 13,219- & 13,228+. I will deal with them in the harshest possible way.

Does anyone know if these are forwarded to the table-keepers occasionally?

The prefered method of communication on these numbers seems
to be several running threads of e-mail. For example, Zimmermann
reports having finished the last C140 (and smaller), and moving on
to C141, with CADO-NFS. There's the epfl ecm effort, four factor
reports so far in November. Joppe Bos says that he's working his
way through the c14x first holes. A recent addition is Henrik Olsen,
seven snfs's on Nov 11; eleven factorizations on Oct 24 and
eight more on Oct 29. If you send an email I could send in your report
to a selection of the people sending factors, with a cc: to you,
after which you could send follow-ups.
