WebA graph isomorphism is a bijection between the vertex sets of two graphs such that two vertices in one graph are adjacent if and only if the corresponding two vertices in the other graph are adjacent. Isomorphic graphs are viewed as being the same graph. Within a graph, two vertices that are joined by an edge are said to be adjacent, or neighbours.
