On this page are computer-accessible forms for the graph C4[ 48, 9 ] =
PX(6,3).
(I) Following is a form readable by MAGMA:
g:=Graph<48|{ {8, 15}, {40, 47}, {16, 23}, {24, 31}, {32, 39}, {1, 9}, {33, 41},
{32, 40}, {17, 25}, {16, 24}, {2, 11}, {39, 46}, {34, 43}, {18, 27}, {7, 14},
{23, 30}, {6, 12}, {39, 45}, {38, 44}, {7, 13}, {22, 28}, {23, 29}, {1, 10},
{36, 47}, {33, 42}, {17, 26}, {4, 15}, {20, 31}, {5, 9}, {37, 41}, {21, 25}, {3,
14}, {38, 43}, {35, 46}, {19, 30}, {6, 11}, {22, 27}, {2, 12}, {35, 45}, {34,
44}, {19, 29}, {18, 28}, {3, 13}, {5, 10}, {37, 42}, {21, 26}, {4, 16}, {36,
48}, {12, 24}, {8, 16}, {40, 48}, {9, 17}, {10, 19}, {15, 22}, {14, 20}, {15,
21}, {9, 18}, {12, 23}, {13, 17}, {11, 22}, {14, 19}, {10, 20}, {11, 21}, {13,
18}, {8, 44}, {1, 41}, {3, 42}, {6, 47}, {4, 46}, {5, 47}, {2, 41}, {7, 44}, {1,
45}, {3, 46}, {6, 43}, {4, 42}, {5, 43}, {2, 45}, {20, 32}, {28, 40}, {7, 48},
{8, 48}, {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} }>;
(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: (25, 26)(27, 28)(29, 30)(31, 32)(33, 35)(34, 36)(37, 39)(38, 40)(41, 45)(42,
46)(43, 47)(44, 48) (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.
