The Sierpiński-Riesel Base 5 Project is a distributed computing project. It was formerly managed by users of mersenneforum.org, and is currently a subproject on PrimeGrid.
Goal
Sierpiński-Riesel Base 5 tries to prove that k=159986 is the smallest possible Sierpiński number base 5 and that k=346802 is the smallest possible Riesel number base 5. To prove this, one must find primes for all k below the smallest known number.
How to participate
Participants in either of the projects reserve a k in the forum, then use NewPGen to sieve and then LLR to PRP test (for primality). After that, users unreserve their k again if no primes are found. Instructions to the project can be found at OmbooHankvalds guidepages.
Status
The correct countings are shown if any k-value got it's own page.
- PrimeGrid Riesel base 5: There are 53 values to prove.
- PrimeGrid Sierpinski base 5: There are -1 values to prove.
