Updated Sieve Files
Sieve files for k*2^n1
Here are the latest sieve files for 4 < k < 10000 and n < 12M. pmin and pmax give a range of what's been completed. We kindly ask that srsieve AND psieve be credited with any primes found with these sieve files. Those are the two sieve programs used in the sieve. Should anyone wish to credit the effort (PrimeGrid) that is perfectly fine, but certainly NOT required. Please note the new file locations. Comcast has discontinued free hosting, so these files are now hosted on PrimeGrid. The main url for these files is now http://www.primegrid.com/sieving/rsp. Because it was requested and especially since PrimeGrid has to pay for outgoing bandwidth, subsets of all the sieves for k < 300 are now available.

Also, are there sieve files for k*2^n+1 as well as k*2^n1? Last fiddled with by sweety439 on 20221113 at 05:16

The files you ask about are tested by PrimeGrid themselves. The files provided here are their "extra" files; the sieve tests +1 and 1 forms at the same time, but PG's efforts look for primes of +1 form and k=3 of the 1 form.

Huh? For me, Firefox, Opera, Chrome and Edge download them all fine.
