Definitions for permutations with an emphasis on permutation patterns and statistics.

- Math.Sym
- Provides an efficient definition of standard
permutations,
`StPerm`

, together with a typeclass,`Perm`

, whose functionality is largely inherited from`StPerm`

using a group action and the standardization map. - Math.Sym.D8
- The dihedral group of order 8 acting on permutations.
- Math.Sym.Stat
- Common permutation statistics, such as
`des`

,`inv`

,`exc`

,`maj`

,`fp`

,`comp`

,`lmin`

,`lmax`

, ... - Math.Sym.Class
- Common permutation classes.
