Come one, come all! This is a very exciting project where we hope to find many top-5000 primes in a short period of time.

With this project, the primary focus will be to do Riesel prime tests of the form k * 2^n – 1 for 300 < k <= 1001 that have not been reserved by others or are not being actively worked on. k < 300 and 1001 < k < 1400 are already being searched by other projects or individuals.

This forum is to coordinate and extend prime searching at Michael Hartley’s originally well-designed 'Prime Search' site that has now gone defunct. It is believed that the prime-searching community originally largely ignored this testing range because there was previously no forum to coordinate sieving and searching. This forum has changed that and has brought testing up to where it should be.

Sieve files have been prepared in advance for all n-ranges. We are running large team drives for all ranges as follows:
  • PRPnet automated testing for 25 k's in k=300-350 and n>2M.
  • Individual-k reservations for k=350-400 and n>2M.
  • PRPnet automated testing and manual reservations for k=400-1001 and n>1M.
Subprojects will include:
  • Testing of other k-values outside the original scope of the project that are significantly behind their neighbors as to how far they have been searched. If necessary, coordination with existing reservations at other sites will be done ahead of time. This is the crux of the entire project. 300<k<=1001 has been searched much less than k<300 and k>1001.
  • In the future, double-checking of n=260K-600K for already completed k-values.
The main two goals of the project relate to all k < 1000 and are as follows:
  • All k's should be fully tested to the top-5000 range at all times.
  • All k's should have their non-top-5000 ranges tested.
Please see other threads in the forum for questions about searching and software.
