The link is invalid.

Also results pages do not open, for example

I enabled the prime tuple database again! at https://boinc.tbrada.eu/spt/explore.php

You can also download all tuples of certain kind into a text file, limited to 200000 at a time. The instructions are there, but here is a example:
https://boinc.tbrada.eu/spt/tuples.php?spt=20&p=1 gives first page of SPT(20), or to get html of the second page
https://boinc.tbrada.eu/spt/tuples.php?spt=20&p=2&ln.

I forgot about the project for a while, thats why tasks run out. I will submit another batch shortly. But first must analyze memory and processor requirements. With bigger numbers, memory estimate and credit multiplier must be increases.

Changes to spt batch 81:

  1. Increase minimum odd-length SPT to be 13 primes long
  2. Do not derive 12-prime TPT from TPT(14)s
  3. decrease estimated flops multiplier to 14
  4. Increase memory requirement to 640 MiB



The credit multiplier was found to be still adequate, and was not changed. Please let me know of problems.
