under the group generated by the following permutations:
a: (2, 6)(4, 8)(9, 187)(10, 192)(11, 189)(12, 186)(13, 191)(14, 188)(15,

106)(98, 102)(100, 104) (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.
