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