[QUOTE=sweety439;520532]Currently, there is [B]NO[/B] "10,323- c271" in the page [URL="http://homes.cerias.purdue.edu/~ssw/cun/who"]http://homes.cerias.purdue.edu/~ssw/cun/who[/URL].[/QUOTE]

And?

If you bothered to pay attention over the last few years you would have observed that
only a few numbers get queued at a time. 10,323- has not been queued yet.

[b]SO WHAT?[/b]

You would also have observed that Greg is generally (with a few exceptions) doing
numbers in order of increasing SNFS difficulty. A small amount of effort would reveal
that there are about a dozen Cunningham numbers smaller than 10,323- that have yet
to be queued.

What is your <censored> obsession with this one number?

[QUOTE=VBCurtis;520472]You suggested this one, and were told it's going to wait until easier ones are done first. Please don't keep asking.[/QUOTE]

See his next post. He can't stop. It's an obsession.

Greg has been in contact about the current effort. He asks us to focus the ECM focus on 2_1084+, 2_2126M, and 2_2150M. He will queue them in a couple of months but they need more ECM.

Greg should add 2,1157+ to his list as well. We'll need to run more ECM. (exponent
divisible by 13 so a sextic works very well)

You might want to ask Bruce Dodson how much work he did with these numbers.

One data point. I know that Arjen ran 20K curves with B1 = 10^9 on all of the
base 2 numbers a number of years ago. You may want to check with him as well.

Certainly, it’s all just a matter of prioritization. Even yoyo likely won’t be able to complete a full t65 on the three composites in two months. But we will do what we can.

We can weave the others into the tapestry.

These are now starting to get some ECM, well at least 2,1084+ so far. I estimate it will take until mid Oct to complete these three at the t65 level. Hoping this meshes with Greg’s queuing plans but there it is.

Planning on queuing 2,1157+, 2,1144+ and 2,2158L next.

Under yoyo is is possible to choose only to ecm from the Cunningham or is it still sending from all sub projects.

Finishing the sieving on 2,1072+ and 2,1076+ should take another 3-4 weeks.
I am guessing that Greg might then queue 2,2126M (same difficulty as 2,1063+).
This should take us to the 2nd/3rd week of September before he would be ready
for one of the currently queued YoYo ECM candidates.

it will still send workunits for all available ecm numbers if you select the ecm subproject
