Exercise 9

Avg difficulty 3.0

A permutation, regarded as a function from the set {1,..,n}\{\hskip 1.00006pt1,..,n\hskip 1.00006pt\} to itself, is one-to-one and onto. Therefore, each permutation has an inverse.

  • Find the inverse of each 22-permutation.

  • Find the inverse of each 33-permutation.
