It should be 43740.

There are 10 ways to pick any 2 out of 5 possible runes. (x10)

Either one of them can be primary. (x2)

Within the primary tree, there are four possible sets of 3 to pick from. (x3x3x3x3)

Within the secondary tree, there are 3 possible sets of 3 and only 2 can be picked.

There are three ways to pick two. (x3)

Within the two sets that are selected, there are 9 possible combinations. (x9).

10 * 2 * (3 * 3 * 3 * 3) * (3 * 9) = 43740
