As of Version 10, most of the functionality of the Combinatorica package is built into the Wolfram System. >>


returns a Hasse diagram of the partially ordered set on size-n permutations in which if can be obtained from by an adjacent transposition that places the larger element before the smaller.


  • To use InversionPoset, you first need to load the Combinatorica Package using Needs["Combinatorica`"].
  • The function takes two options: Type and VertexLabel, with default values Undirected and False, respectively.
  • When Type is set to Directed, the function produces the underlying directed acyclic graph. When VertexLabel is set to True, labels are produced for the vertices.
