(II) A more general form is to represent the graph as the orbit of {64, 69}
under the group generated by the following permutations:
a: (1, 35, 99, 105, 149, 199, 221, 265, 18, 52, 82, 122, 166, 182, 238, 248)(2,

250) (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.
