[QUOTE=xilman;382323]Here are the 13 factors found by Jon Becker and Bob Silverman in the last six weeks or so. The number of composites has now dropped to 280.

Paul[/QUOTE]

Paul managed to uncover two more factoring reports that had gone missing, for 8+7,239 and 8-7,239. He's updated his tables and the number of composites is now 278.

I've been rather remiss at posting updates :redface:

Here's the "recent" work --- almost two months in fact.

There are now 250 remaining composites. The web page has been updated.

Paul

Assuming that no last-minute stragglers appear, the final update for 2014 has just been posted. There are 239 composites remaining in the tables.

These are the discoveries reported to me in the last month.

17 new factors have been found so far this year, all by Jon Becker and Bob Silverman. There are now 222 composites now in the tables. The new tables will hit the web site shortly after this post.

Several numbers have been reserved for 4 months now. What is happening with them?

[QUOTE=R.D. Silverman;395085]Several numbers have been reserved for 4 months now. What is happening with them?[/QUOTE]

For my part, nothing. But I have lost the confirmation codes so I can't unreserve them.

Aha!

Paul, can you do so?

[QUOTE=R.D. Silverman;395093]Aha!

Paul, can you do so?[/QUOTE]Unfortunately not.

I suggest two courses of action. 1) mail Tom Womack and 2) start factoring the numbers in question.

Did you ever do polynomial selection on either of your reserved numbers?

[QUOTE=jyb;395112]Did you ever do polynomial selection on either of your reserved numbers?[/QUOTE]

No. I just ran some ECM (up to ~t40, i.e., a couple thousand curves at B1=3e6).

Okay, thanks. For future reference for everyone listening, all Homogeneous Cunninghams in the current range have received a full t50's worth of ECM, in addition to several hundred curves at B1=110M.
