Sierpinski/Riesel Base 5:

 

What they’re doing

Here are the required steps to get S/R B5 working:

 

Reserve a k:

Sierpinski: To reserve a k then go here and post a message saying what k you’ll choose.

Riesel: Same as above but go here instead.

 

Sieve it:

Sieve the k using NewPGen

 

Test it:

Test the NewPGen file using LLR

 

Report in:

Sierpinski: Open primes.log and see if there is a line saying something like ”xxxxxxx*5^xxxxxxx+1 is prime!”

Riesel: Same as above except you’ll be looking for a ”xxxxxx*5^xxxxxx-1 is prime!”

 

Remember the combination (or copy it) and post the Sierpinskis in this thread and the Riesels in this thread.

If no primes are found, then report how far you tested in the reservation thread and, if you want to continue, you can make a new NewPGen file with new n-ranges.

That’s all there is to using Sierpinski/Riesel Base 5. Not very hard was it?
