| In an undirected graph, (i,j) means that node i and node j are connected with an undirected edge. | |
| The nodes are numbered from 0 to 15, and the edges are: (0,15) (0,11) (0,12) (0,14) (0,8) (0,1) (0,5) (0,3) (0,13) (1,15) (1,11) (1,12) (1,7) (1,8) (1,3) (1,13) (2,4) (2,10) (2,9) (3,15) (3,12) (3,7) (3,5) (3,13) (4,6) (5,15) (5,12) (5,14) (5,7) (5,8) (6,10) (7,15) (7,11) (7,14) (7,8) (7,13) (8,15) (8,11) (8,12) (8,14) (8,13) (11,12) (12,15) (12,14) (12,13) (13,15) (13,14) (14,15). |
