Description
The number of inversions of a permutation.
This equals the minimal number of simple transpositions (i,i+1) needed to write π. Thus, it is also the Coxeter length of π.

Map
initial tableau
Description
Sends an integer partition to the standard tableau obtained by filling the numbers 1 through n row by row.
Map
conjugate
Description
Return the conjugate partition of the partition.
The conjugate partition of the partition λ of n is the partition λ∗ whose Ferrers diagram is obtained from the diagram of λ by interchanging rows with columns.
This is also called the associated partition or the transpose in the literature.

Map
reading word permutation
Description
