Description
The number of saliances of the permutation.
A saliance is a right-to-left maximum. This can be described as an occurrence of the mesh pattern $([1], {(1,1)})$, i.e., the upper right quadrant is shaded, see [1].

Map
complement
Description
The complement of a set partition obtained by replacing $i$ with $n+1-i$.
Map
