Description

The last descent of a permutation.
For a permutation

$\pi$ of

$\{1,\ldots,n\}$ , this is the largest index

$0 \leq i < n$ such that

$\pi(i) > \pi(i+1)$ where one considers

$\pi(0) = n+1$ .

Map

Description

Return the clockwise quarter turn rotation of an alternating sign matrix.

Map

to Dyck path

Description

The Dyck path determined by the last diagonal of the monotone triangle of an alternating sign matrix.

Map
