k=69 is completely checked from n=1 up to n=2416k.
Double check was done from n=1 up to n=100k by D. Broadhurst.

All known primes for all k<300 are listed here. Current limits are given as well (they may not be up to date for k=1, 3, 27, and 121).

Thanks for your interest and happy hunting!

ps. Please inform us about your progress from time to time, and attach your results if possible.
And we'll appreciate if you include our project RPS (Riesel Prime Search) in you prover's code when you report primes.
