Let G be a graph with vertex set V(G) = (v1, V2, V3, V4, 05, 06, 07) and edge set E(G) - (v1v2, v2V3, 0304, V4V5, V₁V1, V3V5, V6V1, V6V2, V6V4, V7V2, V7V3, 07V4} Let H be a graph with vertex set V (H) {U1, U2, U3, U4, U5, U6, U7} and edge set E(H) = {u₁u2, U1u5, U2U3, U2u4, U2U5, U2U7, UzU6, UzU7, U₁5, U₁U6, U5U6, U6U7} Are the graphs G and H isomorphic? If they are, then give a bijection f : V(G) V(H) that certifies this, and if they are not, explain why they are not.
