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.

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