(II) A more general form is to represent the graph as the orbit of {29, 30}
under the group generated by the following permutations:
a: (1, 30, 59, 88, 117, 146, 175)(2, 54, 84, 108, 133, 153, 198)(3, 49, 80, 99,
120, 160, 192)(4, 44, 76, 90, 136, 167, 186)(5, 39, 72, 110, 123, 174, 180)(6,
34, 68, 101, 139, 152, 203)(7, 58, 64, 92, 126, 159, 197)(8, 53, 60, 112, 142,
166, 191)(9, 48, 85, 103, 129, 173, 185)(10, 43, 81, 94, 145, 151, 179)(11, 38,

161, 187)(29, 35, 63, 97, 130, 168, 181) (III) Last is Groups&Graphs. Copy everything between (not including)
the lines of asterisks into a plain text file and save it as "graph.txt". Then
launch G&G (Groups&Graphs) and select Read Text from the File menu.
