And this is the first Sierpinski found for SR5.
Congratulation.

Would you now remove those K from further processing on Prpnet?

No !! We need to search to see that there are no smaller primes on those k.

Right, not from PRPnet (the results start with n>=1,000,000).
But two K's can be excluded from the master 2M-5M sieve file.

I will upload the LLR residues to the sieve server (or I can email them).

This could save some time on the upcoming Challenge - quite a few results will be validated with one test with no-hassle-no-wait credit to the participants.
