the main problem is for low values of N, i.e. the ones you can imaginine
in your head, you can figure out regular convex polyhedra whose points
lie of the sphere and whose sides are all the same shape (i.e. a triangular
pyramid, a cube or diamond, etc. however i'm not convinced you can
construct such shapes for all values of N

yes, but it leaves an unpleasant taste in your mouth afterwards,
or is that just me?
