On this page are computer-accessible forms for the graph C4[ 9, 1 ] = DW(3,3).

(I) Following is a form readable by MAGMA:

g:=Graph<9|{ {6, 7}, {5, 7}, {1, 5}, {2, 6}, {3, 7}, {2, 7}, {2, 4}, {3, 5}, {1, 6}, {3, 4}, {1, 9}, {1, 8}, {2, 9}, {3, 8}, {4, 8}, {5, 9}, {4, 9}, {6, 8} }>;

(II) A more general form is to represent the graph as the orbit of {6, 7} under the group generated by the following permutations:

a: (1, 2)(4, 5)(7, 8)
b: (2, 3)(5, 6)(8, 9)
c: (2, 4)(3, 7)(6, 8)

(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.
