Example: For n = 4 the a(4) = 7 solutions are given by the edge sets
E1 = {(1,5), (1,7), (2,6), (2,7), (2,8), (3,7), (4,8)},
E2 = {(1,5), (1,8), (2,6), (2,8), (3,7), (3,8), (4,8)},
E3 = {(1,5), (1,8), (2,6), (2,7), (2,8), (3,7), (3,8), (4,8)},
E4 = {(1,5), (1,7), (1,8), (2,6), (2,7), (2,8), (3,7), (4,8)},
E5 = {(1,5), (1,7), (1,8), (2,6), (2,7), (2,8), (3,7), (3,8), (4,8)},
E6 = {(1,5), (1,6), (1,7), (1,8), (2,6), (2,8), (3,7), (3,8), (4,8)},
E7 = {(1,5), (1,6), (1,7), (1,8), (2,6), (2,7), (2,8), (3,7), (3,8), (4,8)}.
