Description

The number of occurrences of the vincular pattern |132 in a permutation.
This is the number of occurrences of the pattern

$(1,3,2)$ , such that the letter matched by

$1$ is the first entry of the permutation.

Map

runsort

Description

The permutation obtained by sorting the increasing runs lexicographically.

Map

prime Dyck path

Description

Return the Dyck path obtained by adding an initial up and a final down step.

Map

to 132-avoiding permutation

Description

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