| 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 17, and the edges are: (0,11) (0,6) (0,2) (0,5) (1,7) (1,16) (1,14) (1,17) (1,3) (1,9) (1,13) (1,10) (2,11) (2,6) (2,5) (3,7) (3,16) (3,14) (3,17) (3,9) (3,13) (3,10) (4,8) (4,15) (4,12) (5,11) (5,6) (6,11) (7,16) (7,14) (7,17) (7,9) (7,13) (7,10) (8,15) (8,12) (9,16) (9,14) (9,17) (9,13) (9,10) (10,16) (10,14) (10,17) (10,13) (12,15) (13,16) (13,14) (13,17) (14,16) (14,17) (16,17). |
