The isomorphism class is a non-negative integer number. Graphs (with the same number of vertices) having the same isomorphism class are isomorphic and isomorphic graphs always have the same isomorphism class. Currently it can handle only graphs with 3 or 4 vertices.
graph_from_isomorphism_class(size, number, directed = TRUE)The number of vertices in the graph.

Whether to create a directed graph (the default).
An igraph object, the graph of the given size, directedness and isomorphism class.
