(II) A more general form is to represent the graph as the orbit of {136, 143}
under the group generated by the following permutations:
a: (1, 3, 7, 16, 33, 34, 65, 67, 31, 60, 102, 69, 40, 8, 19, 39, 74, 112, 63,

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.
