(II) A more general form is to represent the graph as the orbit of {2, 3} under the group generated by the following permutations:

a: (2, 7)(3, 11)(4, 10)(5, 16)(6, 15)(8, 23)(9, 22)(12, 32)(13, 34)(14, 33)(17, 43)(18, 46)(19, 50)(20, 49)(21, 51)(24, 60)(25, 62)(26, 66)(27, 65)(28, 71)(29, 70)(30, 76)(31, 75)(35, 68)(36, 85)(37, 89)(38, 88)(39, 57)(40, 56)(41, 97)(42, 96)(44, 104)(45, 103)(47, 52)(48, 107)(53, 117)(54, 118)(55, 102)(58, 78)(59, 121)(61, 127)(63, 86)(64, 129)(67, 135)(69, 137)(72, 128)(73, 139)(74, 80)(77, 122)(79, 144)(81, 138)(82, 146)(83, 132)(84, 131)(87, 112)(90, 101)(91, 134)(92, 133)(94, 105)(95, 120)(98, 149)(99, 152)(100, 151)(106, 153)(108, 158)(109, 113)(110, 143)(111, 115)(114, 145)(116, 142)(123, 140)(124, 148)(125, 136)(126, 159)(130, 156)(141, 155)(147, 157)(150, 154)
b: (2, 4, 7, 10)(3, 6, 11, 15)(5, 9, 16, 22)(8, 14, 23, 33)(12, 20, 32, 49)(13, 21, 34, 51)(17, 27, 43, 65)(18, 29, 46, 70)(19, 31, 50, 75)(24, 38, 60, 88)(25, 40, 62, 56)(26, 42, 66, 96)(28, 45, 71, 103)(30, 48, 76, 107)(35, 55, 68, 102)(36, 57, 85, 39)(37, 59, 89, 121)(41, 64, 97, 129)(44, 69, 104, 137)(47, 74, 52, 80)(53, 82, 117, 146)(54, 84, 118, 131)(58, 87, 78, 112)(61, 92, 127, 133)(63, 95, 86, 120)(67, 100, 135, 151)(72, 94, 128, 105)(73, 106, 139, 153)(77, 110, 122, 143)(79, 114, 144, 145)(81, 116, 138, 142)(83, 98, 132, 149)(90, 125, 101, 136)(91, 99, 134, 152)(93, 119)(108, 141, 158, 155)(109, 111, 113, 115)(123, 147, 140, 157)(124, 126, 148, 159)(130, 150, 156, 154)
c: (1, 2, 17, 43, 7)(3, 24, 122, 32, 4)(5, 35, 137, 46, 6)(8, 52, 107, 62, 9)(10, 12, 77, 60, 11)(13, 79, 127, 85, 14)(15, 18, 69, 68, 16)(19, 108, 117, 21, 20)(22, 25, 48, 47, 23)(26, 130, 147, 135, 27)(28, 82, 81, 128, 29)(30, 140, 59, 58, 31)(33, 36, 61, 144, 34)(37, 118, 102, 101, 38)(39, 57, 56, 93, 40)(41, 134, 133, 149, 42)(44, 154, 139, 80, 45)(49, 51, 53, 158, 50)(54, 89, 88, 90, 55)(63, 112, 111, 142, 64)(65, 67, 157, 156, 66)(70, 72, 138, 146, 71)(73, 150, 104, 103, 74)(75, 78, 121, 123, 76)(83, 114, 113, 143, 84)(86, 129, 116, 115, 87)(91, 97, 96, 98, 92)(94, 105, 120, 119, 95)(99, 126, 141, 106, 100)(109, 145, 132, 131, 110)(124, 160, 148, 136, 125)(151, 153, 155, 159, 152)

(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.
