4 * 4 * 6 * 5 * 4 * 1 = 1920

Bishops have to be of different colors (4 black squares, 4 whites squares).

There is only 1 possible position for the King and Rooks because it has to go
between the Rooks and there are only 3 squares available at that time.

Because the Knights change color when they move they could be interchanged
without any difference then 5 * 4 should be divided by 2 then
total number of positions = 960.
