Does the function PermutationMat have an inverse? that is, if i have a matrix that is the matrix of a permutation, is there some function that will give me that permutation?

There is no function built into GAP, but using the code of

`IsMonomialMatrix' (in lib/matrix.gi) it ought to be very easy to write code

for such a test.
