Thanks for taking on a large effort Vmod. Taking care of that will complete all Sierp b < 39 with CK < 1G to n=25K!

Karsten is currently working on R35 at n=15K and Max is currently working on S39 and I think he said he was at n=~23K the last time I heard. Taking R35, S35, and S39 all to n=25K will complete all Riesel b < 39 and Sierp b < 40 with CK < 1G to n=25K. Unfortunately R39 and R40 will be difficult with over 2400 k's each remaining at n=15K. But S40 will be easier than S39 with 200+ k's less remaining. Once both S39 and S40 are complete to n=25K, we'll have all Sierp b <= 50 with CK < 1G at n=25K!

We could also define the same for CK < 1M. I'll do that at a later time.

Eventually I want to put together a "current project search limits" posting that will encourage fill in efforts such as this.

S78 is complete to n=25K; 106 primes found for n=10K-25K; 201 k's remaining; base released.

[unconnected]

Riesel base 97, k=26354
Done to n=25K, 176 k's remains.
Files attached.

Serge reported in an Email that R96 is complete to n=25K. 123 primes were found for n=2.5K-25K and 52 k's are remaining. The base is released.

I would like to reserve R46 all k's to n=50k

[vmod]

2753*42^50363-1
6838*42^50759-1
9418*42^53023-1
13425*42^53024-1
13632*42^58509-1
386*42^59534-1

36 k's remaining at n=60K, continuing

[KEP]

S58 is sieving 143 remaining k's at 0.47T

S60 is complete to n=50K and is testing 28 remaining k's in the n-range of n=50K-75K

4 new primes to report:

2371*60^31838+1
4269*60^32081+1
2852*60^32142+1
6465*60^37209+1

Gary,i have R79 complete to n=10000 for k=1-50000.il email the results to you either today or tomorrow.

[gd_barnes]

Here is a status from Mathew in an April 10th Email:

R46 is at n=41K; continuing.

No primes to report.

[vmod]

S35 status at n=15K.
124 k's eliminated, 700 k's remaining.

Primes for this range are attached (3 k's gave 2 primes each and are indicated inside the file).

Continuing to n=25K.

Max,

I've added S39 to the recommended bases here, which I should have done in the 1st place but didn't because I thought you were near completion on it. You said about a month ago that you were at n=23K on it. If you aren't done with it yet, can you post an interim status report on it with primes found and a search limit up to n=15K or 20K?

For bases with a lot of k's remaining, I like exactly what vmod did here. Posting an update with attached primes and a search limit every month or so or at nice round search limits along the way helps me spread out the admin effort a little and lets us know that people are still working on their reservations.

I also like what Cruelty does on base 10 and all of his efforts here, at NPLB, and RPS. He reports a status on the last day of every month, regardless of the progress made. Personally, I just report them when they hit nice round search limits.


Thanks,
Gary
