Thanks. This C105 was left over when Bob found a factor of the C161 via ECM. Bob's factor was a P56, which was an interesting find, given the two smaller factors that were missed.

More low-hanging fruit. ECM has left a 118-digit cofactor of 9+7,595L. Anybody who wants a nice small starter job can head on over to [URL="http://www.chiark.greenend.org.uk/ucgi/~twomack/homcun.pl"]the reservation page[/URL] and grab this one.

Updates and Announcements
 

The Homogeneous Cunningham Numbers tables will henceforth be hosted at the following location: [URL="https://www.unshlump.com/hcn/"]https://www.unshlump.com/hcn/[/URL]. Please update bookmarks/records accordingly. The ECMnet server for these numbers will continue to be at ecm.unshlump.com, port 8194.

Can a mod please update the first post in this thread to reflect the new tables location?

Since the last update there have been 116 factors found, shown below. There are now 1300 composites remaining in the tables. Digit counts range from 133 to 307. SNFS difficulties range from 196 to 310 (unless you count octic polynomials, for which there are two composites with difficulty 180.6).

The web site, ECMnet server, and reservation page have all been updated to reflect the most recent information. Happy factoring!

[QUOTE=jyb;523337]Can a mod please update the first post in this thread to reflect the new tables location?[/QUOTE]
Done

Hi Jon, could you please investigate why [url]http://www.leyland.vispa.com/numth/factorization/anbn/UPDATE.txt[/url] only shows up results up to 2019-02-01. Thank you in advance. Carlos

There is no need to investigate. The vispa.com website is obsolete. Go to

[QUOTE=R.D. Silverman;524187]There is no need to investigate. The vispa.com website is obsolete. Go to

Thank you and apologies, thought I had updated my links.

HCN table updates
 

I have updated the tables and ECMnet server for the HCNs. Since the last update 48 factors have been found, shown below. Digit counts now range from 140 to 307, with SNFS difficulties still lying between 196 and 310. There are 1255 composites remaining in the tables.

The web site, ECMnet server, and reservation page all show the latest information I have.

There are few remaining HCN composites which are in an appropriate range for factoring by NFS@Home, and which have had sufficient ECM to justify starting NFS on them. In case anyone is interested in helping to do ECM pre-testing on some of the harder candidates, I am running another ECMnet server (v2) on port 8195 of ecm.unshlump.com for this purpose. Alternatively, if anyone prefers to run ECM on their own, PM me for info on the composites and B1 level.
