Let G be a simple graph that satisfies the following three conditions: (1) the graph G has 12 vertices, (11) the minimum degree 8 (G) ≥ 1, the matching number, a' (G) ≤ 3. (111) (a) (b) Among all the simple graphs that satisfy the three conditions (1). (ii) and (iii), construct one that has the maximum number of edges. Explain why your graph in part (a) has the maximum number of edges among all simple graphs that satisfy properties (1) to (111).
