On this page are computer-accessible forms for the graph C4[ 112, 7 ] = PX(14,3).

(I) Following is a form readable by MAGMA:

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

(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.
