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