# VertexTransitiveGraphQ

yields True if the graph g is a vertextransitive graph and False otherwise.

# Details

• A graph g is vertex transitive if for any vertices v and w of g, there is an automorphism of g that maps v to w.
• VertexTransitiveGraphQ is typically used to test whether all vertices in a graph have identical neighborhoods.

# Examples

VertexTransitiveGraphQ gives False for anything that is not a vertextransitive graph:

VertexTransitiveGraphQ works with large graphs:

## Applications(1)

## Properties & Relations(7)

Every vertextransitive graph is regular:

The graph complement of a vertextransitive graph is vertex transitive:

Use GraphAutomorphismGroup to test whether a graph is vertex transitive:

Find the automorphism group:

Compute the orbit of a permutation group:

Single orbit should permute all vertices:

Use VertexTransitiveGraphQ to test whether a connected graph is edge transitive:

The edge connectivity of a vertex-transitive graph is equal to the degree :

The vertex connectivity of a vertex-transitive graph will be at least :
