On this page are computer-accessible forms for the graph C4[ 88, 5 ] = PX(11,3).

(I) Following is a form readable by MAGMA:

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

(II) A more general form is to represent the graph as the orbit of {8, 15} under the group generated by the following permutations:

a: (1, 3)(2, 4)(5, 7)(6, 8)(9, 13)(10, 14)(11, 15)(12, 16)(81, 82)(83, 84)(85, 86)(87, 88)

a1: (1, 9, 17, 25, 33, 41, 49, 57, 65, 73, 81)(2, 10, 18, 26, 34, 42, 50, 58, 66, 74, 82)(3, 11, 19, 27, 35, 43, 51, 59, 67, 75, 83)(4, 12, 20, 28, 36, 44, 52, 60, 68, 76, 84)(5, 13, 21, 29, 37, 45, 53, 61, 69, 77, 85)(6, 14, 22, 30, 38, 46, 54, 62, 70, 78, 86)(7, 15, 23, 31, 39, 47, 55, 63, 71, 79, 87)(8, 16, 24, 32, 40, 48, 56, 64, 72, 80, 88)
b1: (2, 5)(4, 7)(9, 81)(10, 85)(11, 83)(12, 87)(13, 82)(14, 86)(15, 84)(16, 88)(17, 73)(18, 77)(19, 75)(20, 79)(21, 74)(22, 78)(23, 76)(24, 80)(25, 65)(26, 69)(27, 67)(28, 71)(29, 66)(30, 70)(31, 68)(32, 72)(33, 57)(34, 61)(35, 59)(36, 63)(37, 58)(38, 62)(39, 60)(40, 64)(41, 49)(42, 53)(43, 51)(44, 55)(45, 50)(46, 54)(47, 52)(48, 56)

(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.
