d: (1, 6, 11, 16, 21, 26, 31, 36, 41, 46, 51, 56, 61, 66, 71, 76, 81, 86, 91, 96, 101, 106, 111, 116)(2, 8, 15, 19, 22, 28, 35, 39, 42, 48, 55, 59, 62, 68, 75, 79, 82, 88, 95, 99, 102, 108, 115, 119)(3, 10, 14, 17, 23, 30, 34, 37, 43, 50, 54, 57, 63, 70, 74, 77, 83, 90, 94, 97, 103, 110, 114, 117)(4, 7, 13, 20, 24, 27, 33, 40, 44, 47, 53, 60, 64, 67, 73, 80, 84, 87, 93, 100, 104, 107, 113, 120)(5, 9, 12, 18, 25, 29, 32, 38, 45, 49, 52, 58, 65, 69, 72, 78, 85, 89, 92, 98, 105, 109, 112, 118)

(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.
