The documentation of Permutation.to_matrix
<https://doc.sagemath.org/html/en/reference/combinat/sage/combinat/permutation.html#sage.combinat.permutation.Permutation.to_matrix>
states this:
Notice that matrix multiplication corresponds to permutation
multiplication only when the permutation option mult=’r2l’
I am not sure why exactly it was implemented like this, but I imagine this
makes it generally more predictable, as the conversion to matrices does not
depend on a global option of Permutations.
