## Kn graph

For an undirected graph, an unordered pair of nodes that specify a line joining these two nodes are said to form an edge. For a directed graph, the edge is an ordered pair of nodes. The terms "arc," "branch," "line," "link," and "1-simplex" are sometimes used instead of edge (e.g., Skiena 1990, p. 80; Harary 1994). Harary (1994) …IF it is a simple, connected graph, then for the set of vertices {v: v exists in V}, v is adjacent to every other vertex in V. This type of graph is denoted Kn. For Kn, there will be n vertices and (n(n-1))/2 edges. To determine how many subsets of edges a Kn graph will produce, consider the powerset as Brian M. Scott stated in a previous comment.The number of simple graphs possible with 'n' vertices = 2 nc2 = 2 n (n-1)/2. Example In the following graph, there are 3 vertices with 3 edges which is maximum excluding the parallel edges and loops. This can be proved by using the above formulae. The maximum number of edges with n=3 vertices − n C 2 = n (n-1)/2 = 3 (3-1)/2 = 6/2 = 3 edges
