2. (Graphs, degree sequence) If G is a simple graph with n vertices, then the degree sequence of G is a list a1, a2, a3, . . . , an of the degrees of all of the vertices of G in decreasing order. For instance, the degree sequence of the graph G drawn here is 3, 2, 2, 2, 2, 2, 1, 0. (a) Sketch a graph with the degree sequence 4, 3, 2, 2, 2, 1, and a graph...
1. Draw all non-isomorphic simple graphs with 5 vertices and 0, 1, 2, or 3 edges; the graphs need not be connected. Do not label the vertices of your graphs. You should not include two graphs that are isomorphic. 2. Give the matrix representation of the graph H shown below.
