The classic formulation of this problem is:

        how many triangles can be formed by  8  points in a plane as their vertices if no  3  of them lie in one straight line.

See the lesson  Problems dealing with the product of three consecutive integers  in this site.

Then the answer is  C%5B8%5D%5E3 = %288%2A7%2A6%29%2F%281%2A2%2A3%29 = 8*7 = 56.
