I would like to reserve R95 to n=100K

I have processed the following completed ranges of Mathew's:

R46, n=50K-100K; 3 primes:
870*46^51699-1
3383*46^69524-1
7284*46^73716-1

S48, n=40K-100K; 2 primes:
1099*48^81106+1
841*48^84732+1

R75, n=50K-100K; no primes.

All results for these have been attached.

Reserving S81 and S88 to n=100K.

S45 is complete to n=100K; 6 primes found for n=50K-100K shown below; 36 k's remain; base released.

Kenneth has reported that S58 is at n>=88.7K with some k's having been searched to n=125K. 19 primes have been found for n>50K shown below and 100 k's remain. He is continuing.

Serge has reported that S87 is complete to n=360K; nothing to report; the base is released.

Serge has reported that S49 is at n=265K; nothing to report; continuing to n>=300K.

Status update R48:

n=87k

Continuing to n=100k

S88 is complete to n=100K; no primes were found for n=50K-100K; 12 k's remain; base released.

No primes in 22,000+ tests. That's 2 primes for 30 total k's on 4 bases for n=50K-100K including no primes in almost 40,000 tests for R157/R187/S88, most of which were not top 5000 work. :no: The prime gods have not been kind to me.

On a better note, with the PRPnet 2 drive at n>100K, all bases <= 200 with < 10 k's remaining at n=50K are now at n=100K. I'm slowly working that up to < 15 k's remaining.

base 36 prime
 

Hey all,

I found this prime for Riesel base 36. 96497*36^124805-1. There was some more work done, but the PC that contained the residues was moved before I got to retrieve them. I have no further plans for Riesel 36 at the moment.

Cheers, Willem.

S81 is complete to n=100K; 5 primes were found for n=50K-100K shown below; 12 k's remain; base released.
