Actually it can have even more - in a complete graph, consider any permutation and its a cycle hence atleast n! cycles. Actually a complete graph has exactly (n+1)! cycles which is O(nn) O ( n n). You mean to say "it cannot be solved in polynomial time ...... graphs are connected. Vertices in a graph do not always have edges between them. If we add all possible edges, then the resulting graph is called complete .5. A clique has an edge for each pair of vertices, so there is one edge for each choice of two vertices from the n n. So the number of edges is: (n 2) = n! 2! × (n − 2)! = 1 2n(n − 1) ( n 2) = n! 2! × ( n − 2)! = 1 2 n ( n − 1) Edit: Inspired by Belgi, I'll give a third way of counting this!
