      Hello Group!

      Just two months after improving the CC10 record I discovered the following CC10 which is another 10 digits larger:

      1070828503293*2^(k-1)*239#+1, k=1,..,10; CC10 of second kind with 109 digits.

      This time it also improves the record for 10 simultaneous primes.

      Regards,

        The 5th prime in a CC10 counts there so it's listed as 110 digits.
