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