MeatAxe permutations behave similar to permutations in GAP, e.g., one
can multiply two MeatAxe permutations, the result being again a MeatAxe
permutation. But one cannot map single points by a MeatAxe permutation
using the exponentiation operator ^.
MeatAxe permutations are constructed or notified by MeatAxePerm
MeatAxePerm.
IsMeatAxePerm( obj )
returns true if obj is a MeatAxe permutation, and false otherwise.
