(II) A more general form is to represent the graph as the orbit of {104, 107}
under the group generated by the following permutations:
a: (1, 53, 108, 172, 27, 79, 134, 198)(2, 58, 133, 193, 28, 84, 107, 167)(3, 63,

69, 136, 208, 51, 95, 110, 182)(26, 74, 109, 177, 52, 100, 135, 203) (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.
