I've come to this values for the first 10 N:

[3] 4 [4] 24 [5] 100 [6] 360 [7] 1204 [8] 3864 [9] 12100 [10] 37320

For instance, the combinations for N=4 that I'm assuming are:

[1, 0, A, A] [1, A, 0, A] [1, A, A, 0] [A, 1, 0, A] [A, 1, A, 0] [A, 0, 1, A] [A, 0, A, 1] [A, A, 0, 1] [A, A, 1, 0] [1, 0, 1, A] [1, 0, A, 1] [1, 1, 0, A] [1, 1, A, 0] [1, A, 1, 0] [1, A, 0, 1] [A, 1, 1, 0] [A, 1, 0, 1] [A, 0, 1, 1] [1, 0, 0, A] [1, 0, A, 0] [1, A, 0, 0] [A, 0, 1, 0] [A, 0, 0, 1] [A, 1, 0, 0]

For this test case(N=4), am I missing something ?
