I´m able to bring some of these numbers up to pretest level t40 / t45 if needed. Anything above should be done by yoyo@home.
I´m atm looking at the C309 canidate with YAFU. :smile:
I´ll give it 2-3 weeks until I can send it to yoyo.

The generalized Cullen and Woodall numbers are still available at the same address on port 8194, and have been all along.

Only Rob Hooft, Sam Wagstaff and I have been finding factors recently.

All of these numbers have had more than a t45 already. If you look at the ECMnet server, you can see the (best estimate of the) full ECM work each composite has had. All have had at least 1500 curves with B1 = 43e6.

To which candidate are you referring? There is no C309 among these numbers.

[QUOTE=Batalov;497864]11^265+2^265 has a factor 767284030176677976251245248312291358373195027345435491[/QUOTE]

Well, now digit counts range from 136 to 307. Care to keep going, Serge?

Batalov 2018-10-11 21:17

Nah, I just evened the fingernails.
Now there is a bunch of 136s, not too hard for anyone, literally.

Anyone can open the main page? Struggling since yesterday.

The GCW numbers are somewhat easier. Several thousand still need > 2000 curves each at B1=11M.

It is slow to respond, but it does load for me.

You are right Jon, after 10 mins here. Thank you.

[i]Whew![/i] I was worried. My browser was getting stuck at "contacting ..." and would just sit there. And sit. And sit... Same thing happened a few minutes ago.

Just now, I tried again, and -- hey presto, instant connection! Way to go!
