| 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: (0,13) (0,3) (0,15) (0,4) (0,12) (0,9) (0,14) (0,2) (0,11) (1,15) (1,4) (1,12) (1,9) (1,14) (1,2) (2,8) (2,13) (2,15) (2,12) (2,6) (2,11) (3,8) (3,13) (3,12) (3,6) (3,10) (3,14) (3,11) (4,8) (4,13) (4,15) (4,10) (4,9) (4,14) (4,11) (5,7) (6,8) (6,13) (6,15) (6,10) (6,9) (6,14) (6,11) (8,15) (8,12) (8,9) (8,14) (9,15) (9,12) (9,10) (9,14) (10,15) (10,12) (10,14) (11,13) (11,15) (11,12) (11,14) (12,13) (12,15) (12,14) (13,15) (13,14) (14,15). |
