Graph isomorphism is an equivalence relation on graphs and as such it partitions the class of all graphs into equivalence classes. A set of graphs isomorphic to each other is called an isomorphism class of graphs. See more In graph theory, an isomorphism of graphs G and H is a bijection between the vertex sets of G and H $${\displaystyle f\colon V(G)\to V(H)}$$ such that any two vertices u and v of G are adjacent See more The formal notion of "isomorphism", e.g., of "graph isomorphism", captures the informal notion that some objects have "the same structure" if one ignores individual distinctions of "atomic" components of objects in question.
