No !! We need to search to see that there are no smaller primes on those k. Lennart Last fiddled with by Lennart on 20130603 at 13:06

Right, not from PRPnet (the results start with n>=1,000,000).
But two K's can be excluded from the master 2M5M 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 nohasslenowait credit to the participants.
