##### Creating a graph from LCF notation

LCF is short for Lederberg-Coxeter-Frucht, it is a concise notation for
3-regular Hamiltonian graphs. It constists of three parameters, the number
of vertices in the graph, a list of shifts giving additional edges to a
cycle backbone and another integer giving how many times the shifts should
be performed. See

- Keywords
- graphs

##### Usage

`graph_from_lcf(n, shifts, repeats = 1)`

##### Arguments

- n
- Integer, the number of vertices in the graph.
- shifts
- Integer vector, the shifts.
- repeats
- Integer constant, how many times to repeat the shifts.

##### Value

- A graph object.

##### See Also

`graph`

can create arbitrary graphs, see also the other
functions on the its manual page for creating special graphs.

##### Examples

```
# This is the Franklin graph:
g1 <- graph_from_lcf(12, c(5,-5), 6)
g2 <- make_graph("Franklin")
isomorphic(g1, g2)
```
