Old description:
New description:
Permutation groups used to only handle permutations of `1,..n`, and the
methods permute_rows and friends of matrices coped with this with an ugly
and potentially confusing shift by 1. After this ticket, permutation of
`0,...,n-1` are accepted and handled as can be expected. For permutations
of `1..n` and subsets the behavior is unchanged for backward
compatibility.
This ticket also includes the following changes:
- A rewrite of the documentation
- New documentation on a related method
- Code refactorization to avoid some duplication
- The implementation of M.permute_rows_and_columns(sigma)
