        Guys,

        Primeform gives the following as PRP

        6*k*(2^n - 1 - k ) + 2^n - 1, with n = 4497, k = 8939.
        digit number = 13400.

        A beginner in this business, I would like confirmation of this result from
        someone.

        Thank you.

        Peter Lesala.

          Hi Peter,
          Something must be wrong with your expression as (if we do the substitutions
          for n and k) PFGW says:-
          6*8939*(2^4497-1-8939)+2^4497-1 has factors: 7
          Want to double-check it?

            Hi Mike,

            There is an error in the value of n = 4497, the value should be n = 44497.

            Thanks for the quick response.
