Discrete Mathematics 6: A: Draw a graph with 5 vertices and the requisite number of edges to show that if four of the vertices have degree 2, it would be impossible for the 5 vertex to have degree 1. Repetition of edges is not permitted. (There may not be two different bridges connecting the same pair of vertices.)

Let G be a directed graph on n vertices and maximum possible directed edges; assume that n ≥ 2. (a) How many directed edges are in G? Present such a digraph when n = 3 assuming vertices are 1, 2, and 3. You do not have to present a diagram, if you do not want to; you can simply present the directed edges as a set of ordered pairs. b) Is G, as specified in the problem, reflexive? Justify briefly....
