 graph_from_isomorphism_class {igraph} R Documentation

## Create a graph from an isomorphism class

### Description

The isomorphism class is a non-negative integer number. Graphs (with the same number of vertices) having the same isomorphism class are isomorphic and isomorphic graphs always have the same isomorphism class. Currently it can handle directed graphs with 3 or 4 vertices and undirected graphd with 3 to 6 vertices.

### Usage

graph_from_isomorphism_class(size, number, directed = TRUE)


### Arguments

 size The number of vertices in the graph. number The isomorphism class. directed Whether to create a directed graph (the default).

### Value

An igraph object, the graph of the given size, directedness and isomorphism class.

Other graph isomorphism: count_isomorphisms(), count_subgraph_isomorphisms(), isomorphic(), isomorphism_class(), isomorphisms(), subgraph_isomorphic(), subgraph_isomorphisms()
