Imagine a 3 dimensional grid with N x N x N points.
Place as many points as possible on this grid, such that there are no 3 points in a line (for N = 2, this is of course 8).
How much is it for N = 3, 4 or 5?

(In reply to re(2): N=4? probably not by Tristan)

Oh. Thanks. That makes things easier. Sorry
