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