count_automorphisms {DiagrammeR} | R Documentation

## Get the number of automorphisms in the graph

### Description

Get the number of automorphisms the graph contains. An automorphism of a graph is a form of symmetry in which the graph is mapped onto itself while preserving edge-node connectivity.

### Usage

    count_automorphisms(graph)

### Arguments

`graph` | a graph object of class `dgr_graph`.

### Value

a single numeric value representing the number of automorphisms the graph contains.

### Examples

    # Create a cycle graph
    graph <-
      create_graph() %>%
      add_cycle(n = 5)

    # Get a count of automorphisms
    count_automorphisms(graph)
    #> [1] 10

    # Create a full graph and then
    # count the automorphisms
    create_graph() %>%
      add_full_graph(n = 10) %>%
      count_automorphisms()
    #> [1] 3628800
