ToOrderedPairs[g]
constructs a list of ordered pairs representing the edges of the graph 
. 
Details and Options
- 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 
 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.
