## Calculate all isomorphic mappings between the vertices of two graphs

### Description

Calculate all isomorphic mappings between the vertices of two graphs

### Usage

isomorphisms(graph1, graph2, method = "vf2", ...)


### Arguments

 graph1 The first graph. graph2 The second graph. method Currently only ‘vf2’ is supported, see isomorphic for details about it and extra arguments. ... Extra arguments, passed to the various methods.

### Value

A list of vertex sequences, corresponding to all mappings from the first graph to the second.
