Consider an undirected graph G that has n distinct vertices. Assume n≥3. How many distinct edges will there be in any circuit for G that contains all the vertices in G? What is the maximum degree that any vertex in G can have? What is the maximum number of distinct edges G can have? What is the maximum number of distinct edges that G can have if G is disconnected?
