3)
Let (V, E) be the graph with vertices a, b, c, d, e, f, and
g, and edges ab, ac, bc, bd, be, cd, ce, de, af, df, ag, and eg.
(a) Draw this graph.
(b) Write down this graph's incidence table and its incidence matrix.
(c) Write down this graph's adjacency table and its adjacency matrix.
(d) Is this graph complete? Justify your answer.
(e) Is this graph bipartite? Justify your answer.
(f) Is this graph regular? Justify your answer.
(g) Does this graph have any regular subgraph? Justify your answer.
(h) Give an example of an isomorphism from the graph (V, E) to
itself satisfying that p(a) = a.
(i) Is the isomorphism from part (h) unique or can you find another
isomorphism that is distinct from but also satisfies that (a)
a? Justify your answer.
