3. Do you know of any other Riesel k's base 10 and their covering sets of factors for k>10176?

Also, if you can spare a few mins., would you mind checking my page for a few of the k's that you have searched, their primes and ranges? That would help me greatly. I have included all known info. from several souces on the page (shown at the bottom including you as a contributor) as well as plenty of add'l. info. from ranges that I have searched.
My search has gone to 195,000 with no primes. I am searching all four of the remaining k. BTW, you are missing 7666. As for question #3, no.
