`automorphisms()`

was renamed to `count_automorphisms()`

to create a more
consistent API.

## Usage

```
automorphisms(
graph,
colors = NULL,
sh = c("fm", "f", "fs", "fl", "flm", "fsm")
)
```

## Arguments

- graph
The input graph, it is treated as undirected.

- colors
The colors of the individual vertices of the graph; only vertices having the same color are allowed to match each other in an automorphism. When omitted, igraph uses the

`color`

attribute of the vertices, or, if there is no such vertex attribute, it simply assumes that all vertices have the same color. Pass NULL explicitly if the graph has a`color`

vertex attribute but you do not want to use it.- sh
The splitting heuristics for the BLISS algorithm. Possible values are: ‘

`f`

’: first non-singleton cell, ‘`fl`

’: first largest non-singleton cell, ‘`fs`

’: first smallest non-singleton cell, ‘`fm`

’: first maximally non-trivially connected non-singleton cell, ‘`flm`

’: first largest maximally non-trivially connected non-singleton cell, ‘`fsm`

’: first smallest maximally non-trivially connected non-singleton cell.
