      I have just found the following record Cunningham Chain (1st Kind) length 5 :-

      (2^n)*5864262128*1201#-1 For n=0..4

      The smallest member of this chain has 514 digits and as far as I know is a new record for a length 5 CC (1st Kind).....Although it does fall 99 digits short of the record length 5 CC (2nd Kind)!

      Regards
      Gary
