I have completed b=34 and b=38 to n=100000. (38^90713+1)^2-2 is the only prime.

Almost all of them. See here:

Reserve base 146 to n=20k
What seiving application supports Carol and Kyena numbers, the +2s make it impossible to sieve on NewPgen.
Edit 2: gonna use probable prime testing for the numbers with yafu instead

birtwistlecaleb 2022-03-13 11:54

Edit3: cksieve+pfgw is working!

birtwistlecaleb 2022-03-13 15:06

reserving up to 50000 instead (for the same base i reserved up to 20k)

birtwistlecaleb 2022-03-13 17:13

30k instead, very sorry for all of the changes.

update 3/15
 
Base 10 is at n = 236.1 k, no primes found, continuing. ETA to complete to n = 250k is 1 month.
Considering sieving it to n = 500k, but I would not test the range alone. If I were to do that, would that be an interesting project for a PRPserver?

Caleb,

We appreciate the updates. However it isn't necessary to report updates several times a day or even once a day. Just post a reservation when you begin a base(s). Then when done with the base(s), post the n-range completed and the primes found. The same thing applies to sieving. Otherwise there are too many posts to wade through in the future.

Thanks,
Gary

What does this mean? Are you releasing base 46 at n=37314?

Yes.

What does this mean? Is testing values beyond that failing?

birtwistlecaleb 2022-03-20 12:58

I messed up my input file by accident, and im bored of it already.

Base 10 is up to n = 250k, no primes in the range n = 200k -250k. Releasing the base.
Sieve for n = 250k-500k is at 93 T, probably needs another day and a half to get to 100T. I would imagine this should be sieved to 200 or even 300 T before being tested. I'll provide a file when the sieve is done in the case one wants to do a PRPnet project with it.

I'd like to take base 10 starting at 250K. Not sure how high I'll go, maybe to 500K.
