321 Sieving

There is currently a combined sieving effort under way for both the 3*2^n-1 and 3*2^n+1 forms.

The -1 form has been primality checked to n=5M. Once our current effort on the +1 reaches n=5M, we'll advance both forms in parallel.

We are currently performing a combined sieve for 5M<n<25M. We need to be in the p=1000T range before we advance the primality check beyond n=5M.

If you wish to explore the manual side of 321 sieving, please visit the 321 Sieving Reservation thread for more information. NOTE: This project is outside of BOINC. However, manual BOINC cobblestones are available for those participating. :)

So come join the small band of manual sievers at PrimeGrid and broaden your prime finding knowledge and skills. :)
