If anybody knows who found a p56 factor from 11-8,283 on May 5, apparently by ECM, please let me know.

What's going on with 7-3_361? It is still unfactored in factordb, and it hasn't been removed from the ECM server, but it doesn't appear on Tom Womack's reservation page. Was a factor reported there and nowhere else?

There's a possibility that a factor was found with a composite cofactor and the cofactor was what was reported on the reservations page. I have had this happen.

As far as I can tell, it was inadvertently removed from the reservation page and has never been restored. ECMnet is still working on the remaining C213 composite but only 7399 curves have been completed in the march towards a full t55 (i.e. 17884 curves @B1=110M on ECMnet). With a SNFS difficulty of 305, we need a(nother) lucky ECM hit!

Aha thanks, should have checked further back in the thread. Has anyone informed Tom about this?

Default Time for an update!

The tables and ECMnet server have been updated to reflect all factors reported to me through the end of July 26 (GMT). There were 44 new factors found since the last update, of which 35 completed the factorization of their respective numbers. A factor of 11-8,283 was found anonymously; it appears below and in the update file with a discoverer of "Unknown". If anybody wishes to claim it, please let me know and you will be rewarded with all of the fame and fortune which such a discovery deserves.

There are now 900 composites remaining in the tables. The minimum digit count is now 179. With the usual polynomial degrees, SNFS difficulties range from 229 to 310, with all difficulties below 255 requiring a quartic polynomial. However, there is one composite which has an SNFS difficulty of 211 with an octic polynomial.

Here are the factors found since the last update:
