      Puzzle: find a chain of 13 consecutive p-smooth integers, starting at N,
      with log(N)/log(p) greater than

      log(8559986129664)/log(58393) = 2.71328

      Best regards,

      ... Too hard! It was difficult getting just over 2 for the first time with log(287946949)/log(15823). My only consolation is that the above is also good for 15

        Too hard!

        It was difficult getting just over 2 for the first time with
        log(287946949)/log(15823).

        My only consolation is that the above is also good for 15 consecutive 15823-smooth integers.
