Description

The number of reduced words for a permutation.
This is the number of ways to write a permutation as a minimal length product of simple transpositions. E.g., there are two reduced words for the permutation $[3,2,1]$, which are $(1,2)(2,3)(1,2) = (2,3)(1,2)(2,3)$.

Map

Description

Return the permutation obtained by reading the entries of the tableau row by row, starting with the bottom-most row in English notation.
