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

constructs a list of ordered pairs representing the edges of the graph g.


  • ToOrderedPairs functionality is now available in the built-in Wolfram Language function EdgeList.
  • To use ToOrderedPairs, you first need to load the Combinatorica Package using Needs["Combinatorica`"].
  • If g is undirected each edge is interpreted as two ordered pairs.
  • An option called Type that takes on values Simple or All can be used to affect the constructed representation.
  • Type->Simple forces the removal of multiple edges and self-loops. Type->All keeps all information and is the default option.
