I count 60 unfinished numbers from the 1987 hardcover edition of the Cunningham book.

Agreed. I had 68 original composites with 8 factored, leaving 60 remaining numbers yet to be factored. So we match there.

And we both have 46 numbers in Yoyo’s queue. Your list appears to match mine.

The difficulty of 2,2398M (SNFS 361) is beyond NFS, and it has been ECM’d to t65 AFAIK. Ryan agreed to look at it last April but his progress is unconfirmed. So we seem to be in agreement here as well.

The remaining 13 are all works in progress. Suggest we wait for Greg to update the 16e/f queue display - it is wildly out of date. Your listed status for many of these is more accurate than mine, but there is still uncertainty with a few of them.

I wrote that it is beyond the capability of NFS@Home. It is clearly not past the
capability of NFS --> i.e. Kleinjung et.al finished all 2^n-1 for n < 1200.

I don't fully agree with your assessment of Greg's queue. There is only one number queued but not listed.
It does fail to show that two numbers were finished.

What is the status of 2,2158L and 2,1144+? Sieving or awaiting LA?

Presumably 2,2330M is currently sieving. Just seeking confirmation. TYIA.

2,2158L is sieving. 2,1144+ is waiting for LA. I expect 2,2158L to take ~3 more weeks.

The forum provided a polynomial for 2,1165+. I'm not sure what Greg will do next.

You can always check current efforts at:

Right now my queue has wus for 2,2158L from 1513M to 1778M but still more than 1.13M wus available on the server. Remember each wus sieves a 2k space. Not sure how far are we going to sieve 2,2158L but there might be already another number queued.

[swellman]

That’s great news. Presumably once 2,2158L finishes sieving, 2,2330M and 2,1165+ will (eventually) follow.

Looking ahead, should 16e need to be fed, there’s the quartic 2,2210M (SNFS 266) which was ECM’d to a full t65.

Note 2,2398M is fully ECM’d, awaiting action. With a SNFS difficulty of 361, it might be waiting for some time.

There remain 46 numbers in Yoyo’s queue, with 10 currently being worked/completed and 36 awaiting ECM. I estimate all 46 should be finished with the first round of ECM t65 ~March 2021. Five more rounds of ECM will take until ~Dec 2027 if nothing changes.

The ECM effort takes 3 days to run through 90% of a trial, then another 8 days
to finish the remaining 10%....... Perhaps this might get fixed, eventually.

Greg said that he would do 2,2210M, but he did not place it on the status page.

There is also a slightly bigger quartic: 2,2230M if Greg chooses to do it. And 2,2162L,M
are slightly smaller than the largest number done so far. After that, they are probably
beyond NFS@Home. I doubt that Greg wants to spend 2-3+ months sieving a number.

To finish the rest, a factory approach would be best, but there would be 44 of them....
Probably too large an effort for anyone at the current time.

I am hoping that the ECM effort will pick off 3 to 4 of them.

Greg added more 2,1072+ wus.

Just a few to bring the matrix down a bit. And I'm queueing all of 2,2210M and 2,2230M before 2,1165+.

Great. In terms of postprocessing backlog, how are we?
