| 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 12, and the edges are: (7,8) (12,10) (0,1) (0,2) (10,5) (8,1) (2,12) (5,11) (11,8) (10,7) (9,12) (9,0) (6,2) (0,10) (3,7) (9,4) (6,4) (2,1) (0,12) (3,5) (9,6) (8,0) (2,3) (1,5) (4,3) (12,3) (6,0) (2,10) (9,3) (0,11) (2,4) (12,5) (3,6) (11,7) (8,5) (1,3). |
