Once in a while, you have a good idea. This has been done.

Another good idea for me is add the 2nd Riesel problem to CRUS to make the Riesel and Sierp sides at CRUS equivalent, and this has also been done.

Also I have another idea: Show the status for k <= 12 in a CRUS page like the top20 page and the the condensed table.

Also, you can also consider to include k=1 in the Sierpinski conjectures in the case when it has a known prime,

e.g. for S44, the primes can be:

Code:

1 (16)
3 (9)
2 (1)

and for S56, the top 10 primes can be:

Code:

13 (6)
7 (6)
3 (5)
16 (2)
15 (2)
1 (2)
18 (1)
17 (1)
12 (1)
11 (1)

Gary-
See what happens when you encourage him?

Oh, I'm aware.

No and no.

Don't press your luck.

Quick update for S63 sieving (n=25k-50k, all remaining k values). Sieve has hit P=1e12 with found factor rate of ~3 sec/factor. Needs to get to ~30 secs/factor, so continuing on toward P=1e13, stopping whenever the time per factor is sufficiently high.

Also quick update for starting R726 as a new base. Using the new base script, I'm currently at k=2655790.

Switch to the latest srsieve2cl for a 10% speed boost.

I did, and I'm seeing about that much

As I return to testing R36, I note that my sieve file is CPU-sieved, to a depth of roughly 2e14. With ~30 k's, is this a candidate to have sieved by yoyo? My sieve file is 425k-2M base 36 (shows as 850k-4M base 6).

With nearly 1M tests, the file would be too big for Yoyo.

The file that is posted on the reservations page is sieved to 1e14. I assume you must have sieved it further.

I can probably sieve this deeper after I complete sieving the current conjectures I am working on.
