Never thought those 60 composites few months back were now almost completely factored ([URL]http://www.chiark.greenend.org.uk/ucgi/~twomack/homcun.pl[/URL]). Between post-processing lets point our cores to ecmserver.

3 cores for 10 days pointed to ECM server.

Hi Paul,

The ECMnet server for these numbers appears to be down right now.

Thanks.

[QUOTE=jyb;449040]Hi Paul,

The ECMnet server for these numbers appears to be down right now.

Thanks.[/QUOTE]

And wouldn't you know it, almost immediately upon posting, it comes back up again. Never mind.

[QUOTE=jyb;449042]And wouldn't you know it, almost immediately upon posting, it comes back up again. Never mind.[/QUOTE]I had to reboot the machine after a security update. You caught it in the couple of minutes when it was down.

Volunteer wanted
 

As you may have guessed from the significant period of inactivity when the tables have not been updated, I would like someone else to take over the maintenance of the HCN tables. The two main contributors have already been contacted, one of whom reports that he doesn't have the necessary facilities. The other has yet to respond.

Any volunteers to take over? I'll do what I can to make the transition as easy as possible.

An update! Huzzah!
 

At long last, here's an update. There are some changes worth mentioning to the tables and the project as a whole:

1) I am taking over stewardship of the tables. Any updates or corrections should be directed to me. The tables are still being hosted on Paul's site, so the URL remains the same. See the main page for contact information. [url]http://www.leyland.vispa.com/numth/factorization/anbn/main.htm[/url]

2) We have added new entries to all appropriate tables for Aurifeuillian factorizations. This adds 400 new composites to the tables. All existing entries for numbers that have an Aurifeuillian factorization have been redone to show the full breakdown. Exponent limits in each table have been increased for such numbers to bring Aurifeuillian factors up to 1024 bits. Details on this can be found by following the relevant link on the main web page.

3) Tom's reservation page is currently not active, but we hope to get that up and going soon.

4) There is an ECMnet server running on 83.217.167.177:8195.

5) The following shows all changes to the tables since Paul's last change, about a year and a half ago. The entries marked with an asterisk represent corrections to existing lines in the UPDATE file. All others are new lines. Factors credited to "FDB" were found in the FactorDB without any attribution. If you know who entered any of them, please submit a report and the appropriate line can be corrected.

6) There are currently 1587 composites in the tables. Digit counts range from 117 to 307, and SNFS difficulties range from 196 to 310.

7) If anybody wants help generating SNFS polynomials for the Aurifeuillian composites, let us know.
