Description

The length of the exterior of a permutation.
The exterior of a permutation is the longest proper prefix that is also a suffix, when viewed as a pattern. In other words, the length of the exterior of a permutation

$\sigma$ of length

$n$ is the largest

$i < n$ such that the first

$i$ entries of

$\sigma$ are in the same relative order as the last

$i$ entries of

$\sigma$ .

Map

to composition

Description

The composition corresponding to a binary word.
Prepending

$1$ to a binary word

$w$ , the

$i$ -th part of the composition equals

$1$ plus the number of zeros after the

$i$ -th

$1$ in

$w$ .
This map is not surjective, since the empty composition does not have a preimage.

Map

to 132-avoiding permutation

Description

Sends a Dyck path to a 132-avoiding permutation.
This bijection is defined in [1, Section 2].

Map

bounce path

Description

The bounce path determined by an integer composition.
