Riesel Base 42
 

Riesel base 42 is now complete to n=50k
Primes found 8

5677*42^33413-1
14576*42^34066-1
10276*42^34186-1
1160*42^35704-1
6333*42^40654-1
12151*42^42450-1
8384*42^44832-1
2304*42^48567-1

I will email the prime file, the out file, and a sieve file for 50k to 100k sieved to 600G

I am releasing the base.

Thanks for the contribution Mathew.

Meanwhile: Reserving S58 for n=10K-25K.

...slowly pounding away on these b<=200 bases that are at n<25K. :smile:

Reserving new Riesel and Sierp base 78 to n=25K.

If I correctly have understood Riesel base 97 is not reserved by anyone. So I want to reserve it - to 10k initially.

That is correct. Good luck.

R78 is at n=10K; 147 k's remaining; continuing to n=25K.

S78 is at n=10K; 307 k's remaining; continuing to n=25K

Detailed and way more factbased status update as of February 26th 2010:

Regarding Sierpinski base 63 (all k's): Estimated completion date is June 20th 2010.

KEP

R91 is complete to n=25K; 35 primes found for n=10K-25K; 88 k's remaining; base released.

Not too bad for a conjecture of k>220K! :smile:

S93 is complete to n=25K; 48 primes found for n=10K-25K; 114 k's remaining; base released.
