[QUOTE=VictordeHolland;507395]Becker considers me a spammer :surprised:(I've removed the hyperlink so the real spammers/bots don't spam him more).[/QUOTE]

Sorry about that! FWIW, I did actually receive your email, at 23:47 GMT. Thanks for the factor.

Update!
 

The following are all factors reported to me since the last update, through Feb. 1st. The website has been updated. Any factors reported after that date will appear in the next update. The ECMnet server is still showing these found factors; it is awaiting some attention from xilman. But it is still handing out composites at the appropriate B1 level, so feel free to use it for ECM work.

There are 61 factors shown here, and as of this update, there are 1450 composites remaining in the tables.

Can’t seem to unreserve 9+5_322 since the code doesn’t work.

Over the last few years the [url]www.leyland.vispa.com[/url] web site has become ever more unreliable. A couple of months ago my ISP, Vispa Ltd, told me that I was half of their entire customer base for personal web sites and that support was commercially unviable. I understand that POV and am pleased that I was able to exploit that particular freeby for so long. However, all good things come to an end (other than sausages, which come to two) and the HCN page has now migrated.

Please use [url]https://brnikat.com/nums/anbn/main.htm[/url] from now on.

Indeed, that will be fixed with the next update. Paul is no longer hosting those particular tables, so that link will probably instead go to the official Cunningham numbers site at Purdue.

Tables update
 

Below are the factors that have been reported to me since February 1, and through April 22. Factor reports from April 22 until today will appear in the next update, coming soon. The web site has been updated appropriately. Make sure you are using Paul's new site: [url]https://brnikat.com/nums/anbn/main.htm[/url]. (The old site appears to be still alive, even more so than it had been in a while, but its content is outdated.)

As noted on the project web page, there is now a new location for the ECMnet server. It is running on ecm.unshlump.com, port 8194.

There are 59 factors shown here, and as of this update (i.e. as of April 22), there are 1400 composites remaining in the tables.

Small(ish) factors still available
 

The ECMnet server reported a 45-digit factor found last night. And earlier this month two 46-digit factors were found. So there is apparently still some relatively low-hanging fruit in these tables. If you want to help find it, point your ECMnet v2 clients at ecm.unshlump.com:8194.

Also, this last factor left a 119-digit composite, so anybody looking for a quick GNFS job can reserve it over at [url]http://www.chiark.greenend.org.uk/ucgi/~twomack/homcun.pl[/url].
