WebJul 12, 2024 · Two graphs G1 = (V1, E1) and G2 = (V2, E2) are isomorphic if there is a bijection (a one-to-one, onto map) φ from V1 to V2 such that {v, w} ∈ E1 ⇔ {φ(v), φ(w)} ∈ E2. In this case, we call φ an isomorphism from G1 to G2. Notation Weborder 4 then G is cyclic, so G ˘=Z=(4) since cyclic groups of the same order are isomorphic. (Explicitly, if G = hgithen an isomorphism Z=(4) !G is a mod 4 7!ga.) Assume G is not cyclic. Then every nonidentity element of G has order 2, so g2 = e for every g 2G. Pick two nonidentity elements x and y in G, so x2 = e, y2 = e, and (xy)2 = e.
