On this page are computer-accessible forms for the graph C4[ 120, 2 ] = C_120(1,11).

(I) Following is a form readable by MAGMA:

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

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

(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.
