Sierp base 42 is at n=22K; 46 k's remaining; continuing to n=25K. An extremely stubborn base that has only had 3 primes out of 49 k's remaining for n=15K-22K.

Sierp base 70 is complete to n=25K; 6 k's remaining; now unreserved.

Sierp base 100 is at n=12K; 8 k's remaining; continuing to n=25K.

After these are done, that will leave Sierp bases 46, 80, 81, & 88 remaining to take up to n=25K. After that, I'll likely work on getting more of the Riesel bases < 100 up to n=25K.

Is expanding the Sierpinski base 63 reservation to at least n=131072 (2^17), is expecting to have all k's tested to n=5000 in less than 1 month and after that a huge sieving of all remaining k's can possibly begin for either the entire remaining n-range or for at least a part of the n-range :smile:

KEP

Sierp base 42 is complete to n=25K; 43 k's remain; unreserved.
Sierp base 100 is complete to n=25K; 5 k's remain; unreserved.

New reservations to bring more bases up to n=25K:

Riesel base 46 for n=10K-25K. I'll be able to sieve it in conjuntion with Sierp base 46 that I currently have reserved for n=15K-25K.

Sierp base 61 for n=16K-25K.

Riesel bases 75 and 80 for n=10K-25K. I'll be able to sieve Riesel and Sierp base 80 together for that n-range.

Riesel base 87 for n=20K-25K.

This leaves me with the following reservations for bases > 32 to n=25K:
Riesel bases 46, 75, 80, & 87
Sierp bases 46, 61, 80, 81, & 88

Riesel base 80 is at n=12K; 5 k's remain; continuing to n=25K

Sierp base 80 is at n=12K; 29 k's remain; continuing to n=25K

Riesel base 75 has now been fully sieved for n=10K-25K. I will start on it after finishing Riesel base 80.

Riesel base 80 is complete to n=25K; 4 k's remain; unreserved.

Sierp base 80 is at n=17K; 26 k's remain; continuing to n=25K.

Starting on Riesel base 87 for n=20K-25K. I'll do that before Riesel base 75 for n=10K-25K, which I will do after that.
