## Creating a graph from LCF notation

### Description

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 http://mathworld.wolfram.com/LCFNotation.html for details.

### 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.

A graph object.

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