What are k5 vk5 e and k5 note that the symmetry of k5

Question

Question: 1. Draw P2 ∪C3.

2. What are K₅ \ v,K₅¯ \ e, and K₅? (Note that the symmetry of K5 means that it doesn't matter which vertex is chosen to be v or which edge is chosen to be e.)

3. Choose one of the graphs pictured in this chapter (other than the one in Figure) and encode it using vertex/edge lists, as an adjacency matrix, and using vertex/adjacency lists.
