If there had been 6 stones of each color, then there would have been 3^6 = 729 patterns total. But there are only 5 stones of each color. So all black, all red and all white are not possible. i.e 3 patterns not possible.

729-3=726 possibilities.

I hope i dont get such nerve wreckers in the real test. what is the source of this question ?
