v2.0.2

A LaTeX package for symmetric group combinatorics, including Young diagrams, tableaux, tabloids, skew tableaux, shifted tableaux, ribbon tableaux, multitableaux, abacuses.

This package provides commands for drawing Young diagrams, tableaux, abacuses, which are common objects in algebraic combinatorics and representation theory. These commands are intended to be easy to use and easy to customise. In particular, TikZ styling can be added to the components of these diagrams and common conventions and idioms are supported using a key-value interface. All diagrams can be used as standalone commands or as part of tikzpicture environments.
