When I get to 3M on my current set of numbers, I was going to take another batch and wanted to make sure I have the right list. The first block available starts the number after the last one I reserved. That was 213642298225841 so the first available is k=702943047930463?
For running srsieve, instead of running k=702943047930463 at base 2, I should run k=5623544383443704 at base 4096 (from the line in low4096.txt). The k at base 4096 is not a straight scaling from the k at base 2 due to the way the list was generated with a covering set? |

1) when using base=4096 around 2.25M bits (and may be even lower than that) LLR starts using generic FFT instead of zero padded FFT. If you convert it back to base 2 then LLR uses zero padded FFT. To avoid this bug you will have to switch everything back to base 2 once you are done sieving. (Switching to base 4096 results in faster sieving but use it only if you have scripts to deal with the above). 2) Some of the numbers I generated (247k below) when using the covering set from factors of 2^1440-1 have 2 numbers left instead of 1. You will have to account for this when you select the ks from low4096.txt. The following 247ks will have to be converted to 2k per base 4096. (An oversight on my part when I generated the low4096.txt file) The simplest method of creating a base=4096 file or using this method is to sieve using srsieve (for base2 with the original base2 k's) till 1M. Then using a script to convert the remaining numbers to base 4096 (or any other 2^n base) and then sieve till 1T with srsieve and then convert back to base2. Code:

Coding and scripting is fine, it's my math that's suspect
 Thanks for the info. |

I'll go ahead and reserve the next 100 starting at 702943047930463 and minus 695126702655403 which has been checked. I have a slow machine that can do sieving while waiting.
