Consider the following two graphs $G_1$ and $G_2$.
Are $G_1$ and $G_2$ isomorphic?

• If no, explain why (you could bring one differing feature that prevents isomorphism from those features we've looked into). Be specific by referring to the given graphs' data.
• If yes:
  1. List the matching vertices of the graphs, and
  2. Construct their common adjacency matrix.
