Riesel base 49
 

Hi everyone,

I've finished my reservation for base 49 Riesel. I did not find a prime, there is 1 k remaining and the reservation is up for grabs. I've attached some of the residues.

Cheers, Willem

Riesel base 40
 

Hi all,

here are the remaining k for riesel base 40. I have taken this to n = 5000, I won't go further. As a double check I've done the range n = 1 to n = 1000 twice. They really don't have primes. I did not double check those k that were prp with n < 1000. If you like, I can post the script I use to generate the k's.

Cheers, Willem.

Hi all,

here are all the primes I found for Riesel base 40. After finding PRP I've also proved them prime.

Try and find the pattern! Willem.

"Try and find the pattern! Willem."

Don't get me started on that. I'll be up all night. lol

The pattern is that I don't see any primes for n<1000 nor for n>5000. lol Anyway, I'm assuming that this is for n=1000-5000. Correct? I also assume that I need to run the n<1000 primes myself. On base 3, I just have people send me the n>1000 primes because the file of smaller primes is too huge.

I don't know how big the file of n<1000 primes is. If it is < ~5 MB compressed, can you Email it to me? That'd save me a little time. For base 3, it's just too big but I'm thinking it wouldn't be so big here.

How high did you test it? The results only go up to n=180K but you had it reserved to n=200K.

How is it that n=1 to n=1000 does not have primes? Are you saying that it only has prp's but no primes? :-)
