Description

The number of very big descents of a permutation.
A very big descent of a permutation

$\pi$ is an index

$i$ such that

$\pi_i - \pi_{i+1} > 2$ .
For the number of descents, see St000021The number of descents of a permutation. and for the number of big descents, see St000647The number of big descents of a permutation.. General

$r$ -descents were for example be studied in [1, Section 2].

Map

Simion-Schmidt map

Description

The Simion-Schmidt map sends any permutation to a

$123$ -avoiding permutation.
Details can be found in [1].
In particular, this is a bijection between

$132$ -avoiding permutations and

$123$ -avoiding permutations, see [1, Proposition 19].

Map

to 321-avoiding permutation (Billey-Jockusch-Stanley)

Description

The Billey-Jockusch-Stanley bijection to 321-avoiding permutations.

Map

to Dyck path

Description

Sends a partition to the shortest Dyck path tracing the shape of its Ferrers diagram.
