  1. Start with 1 and 2, and subtract (1+2) from the sum 26:

    26 - (1+2) = 23.

    Now, since the largest number used will be 12 and we've just used 1 and 2, the remaining edge number must be 11:

    23 - 12 = 11

    So the first edge set is {1,2,11,12},
    the next set is {1,3,10,12}, and
    the next is {1,4,9,12}
    . . . .
    . . . .

    Thus we get

    {1,2,11,12}
    {1,3,10,12}
    {1,4, 9,12}
    {1,4,10,11}
    {1,5,8,12}
    {1,5,9,11}
    {1,6,7,12}
    {1,6,8,11}
    {1,6,9,10}
    {1,7,8,10}

    {2,3,9,12}
    . . .
    . . .
    {5,6,7,8}
