This is more or less the problem of packing n equal spheres in a cube.
There is a lot of literature on this. You can use a simulated
annealing to find good enough solutions. You just need 15 lines of
code or less. But it's going to be slow if n is not very small. A fast
language (or Psyco) is better for that.
