Thanks for the great progress Ian.

One thing you might consider doing for efficiency gains is sieving both Riesel and Sierp of the same base together if the # of k's remaining and the current search range are not too much different. Srsieve and sr2sieve can handle that. You can even start the two sides from a different n-range and still gain overall efficiency if the current search depth isn't too much different. For doing that, you'd just have to start them separately in srsieve before merging them together and continuing with sr2sieve.

Base 60 would have been a pretty good one to do that on. Other bases that you could do that on in the future would be 42, 46, 55, 61, 70, and 75. Additionally, even though they are currently at different n-depths, bases 48 and 60 could also be sieved together in sr2sieve after starting each separately in srsieve from a different n-depth.

That was part of the reason I was trying to get many of the higher bases on both sides up to n=25K. I was able to utilize that tact on just 2-3 of them but now the 2 sides are a little more synced up and it can be used on more of them.

I just thought of it again now or would have mentioned it earlier.

They are starting to get a little thin. I need about 30 more to get under 300 for this base. I intend to stop at 50,000, which is as far as I had sieved.

k=642 already had a prime at n=34348 so that makes 10 additional k's with primes in this batch for 330 k's remaining at n=40K.

With just 10 in an n=5K range, unfortunately it looks a little unlikely that you'll get to < 300 k's remaining at n=50K. I've had the same thing happen with Sierp base 31. At n=10K, I thought I'd get to 900-1000 k's remaining at n=25K. It then began to look like ~1100, then 1100-1125. Now, as I near n=20K, it's looking more like it will be 1125-1150 will remain at n=25K. I was hoping to get to < than the 1123 k's remaining for Sierp base 19 at n=25K. I think it's going to be close but will probably come in just a little above that...still remarkable for a conjecture 8+ times as high!

Great work! All Riesel bases < 40 except 3/7/15 are now at n>=10K.

I'm going to assume that you are not showing all remaining k's for those bases. Either that or I reading the conjecture pages wrong.

No, they are all shown for all bases. If a base has > 25 k's remaining, there is a link to the page that shows the k's. Keep in mind that bases 3, 7, and 15 are excluded from my comment.

The only time they might not be shown is if it says "to be shown later" or "testing just started" but that is not the case for any bases < 40.

[gd_barnes]

After an Email exchange with Ian, I realized that what I said here wasn't quite clear. To be more clear:

All k's that are remaining are shown on the web pages for all bases IF THOSE K'S HAVE BEEN ALREADY TESTED.

Obviously there are billions of k's still remaining on bases 3, 7, 15 that are NOT shown as remaining because they have NOT been tested yet. It would not be reasonable (or even possible?) to show them all. The same thing applies to any base where testing has just started, not started but I want to show other info. about the base, or where I only know the # of k's remaining but not the specific k's.
