OBSOLETE COMBINATORICA PACKAGE SYMBOL

# Isomorphism

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

Isomorphism[g,h]
gives an isomorphism between graphs g and h if one exists.

Isomorphism[g,h,All]
gives all isomorphisms between graphs g and h.

Isomorphism[g]
gives the automorphism group of g.

## DetailsDetails

• Isomorphism functionality is now available in the built-in Wolfram Language function FindGraphIsomorphism.
• To use Isomorphism, you first need to load the Combinatorica Package using Needs["Combinatorica`"].
• This function takes an option Invariants->{f1,f2,}, where f1,f2, are functions that are used to compute vertex invariants. These functions are used in the order in which they are specified.
• The default value of Invariants is .
