      Let n=2
      Phi(2^2) = 2 = 2.(2-1)
      => k=2
      => k/n = 2

      Now, as someone with "limited intelligence", I think that 2 actually
      _is_ an integer, but am prepared to be proved wrong using your Most
      Valued mathematical techniques. After you've read Matthew 7 verse 5,
      that is.
