On this page are computer-accessible forms for the graph C4[ 30, 2 ] = C_30(1,11).

(I) Following is a form readable by MAGMA:

g:=Graph<30|{ {2, 3}, {28, 29}, {26, 27}, {24, 25}, {12, 13}, {10, 11}, {4, 5}, {6, 7}, {8, 9}, {14, 15}, {16, 17}, {18, 19}, {20, 21}, {22, 23}, {1, 2}, {29, 30}, {25, 26}, {13, 14}, {9, 10}, {5, 6}, {17, 18}, {21, 22}, {3, 4}, {27, 28}, {11, 12}, {19, 20}, {4, 15}, {16, 27}, {1, 12}, {3, 14}, {17, 28}, {19, 30}, {2, 13}, {7, 8}, {18, 29}, {23, 24}, {4, 23}, {8, 27}, {1, 20}, {11, 30}, {9, 28}, {3, 22}, {5, 16}, {7, 18}, {13, 24}, {15, 26}, {2, 21}, {10, 29}, {6, 17}, {14, 25}, {8, 19}, {12, 23}, {5, 24}, {11, 22}, {9, 20}, {7, 26}, {1, 30}, {10, 21}, {6, 25}, {15, 16} }>;

(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: (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)
b: (2, 12)(3, 23)(5, 15)(6, 26)(8, 18)(9, 29)(11, 21)(14, 24)(17, 27)(20, 30)
c: (2, 20)(3, 9)(4, 28)(5, 17)(7, 25)(8, 14)(10, 22)(12, 30)(13, 19)(15, 27)(18, 24)(23, 29)

(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.
