Answer 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}
