I don't see how it's an issue of the number of subsets. 

It's at least partly an issue of the number of points belonging to the subsets. For example, in your case of 250 points, suppose you said that you wanted each of the 6 subsets to contain 249 points. This is equivalent to the problem of choosing one of the 250 points to remove so that the remaining 249 are evenly distributed over the sphere, which is again clearly impossible.
