is an option that can be used in ShowGraph to display a vertex number in a certain position relative to the vertex.


  • VertexNumberPosition functionality is now available in the built-in Wolfram Language function VertexLabels.
  • To use VertexNumberPosition, you first need to load the Combinatorica Package using Needs["Combinatorica`"].
  • By default, vertex numbers are positioned to the lower left of vertices.
  • VertexNumberPosition can be set as part of the graph data structure or in ShowGraph.
