Gongol #dimensions #4d #tibees

You might call this a ball but you might be wrong. It's only a ball if you're talking about the solid shape inside of here. If you're talking about the surface only then that's a sphere. We recently met the globe which is the 40 equivalent of the sphere. The globe is the set of points in the fourth dimension that are the same distance away from a common center. So what would we call a 40 ball? Not just the surface but the thing we would get if we filled in a solid globe. The answer is a gongle and while we're here a shout out for the pentorb hexorb, heptorb, octorb, enorb and nickob which are the hyper balls of other dimensions up to 10. At least that's the names according to various hyperspace wikis. I think that mathematicians are happy to just call them in balls where in is the number of dimensions. Can you think of any better names?
