      Congrulations from me, too.

      I have updated the CC record list in the file section. Jens Kruse
      Andersen will update the corresponding web page.

      In addition the following CC records have been improved:

      CC15 by Alm/Andersen from 22 to 23 digits.
      CC6 by myself from 336 to 417 digits.

      The new CC6 record is also a new record for the largest known case of
      6 simultaneous primes.

        Indeed. Congratulations on your big CC6:
        33692909611*977#*2^n-1, n=0..5

        This is not as easy to beat as last time (where I improved Dirk's CC6 record
        before it was published).
        Your new record is safe from me for the moment.
        http://hjem.get2net.dk/jka/math/simultprime.htm has been updated.
