I feel like Pentagons should be allowed as Rectangles and Hexagons are allowed, and a Pentagon is inbetween the two. Also, are we only allowed to use regular polygons, or are we allowed to have any shape as long as it fits the point restriction?
Ellipses is just a circle but it is elongated which is allowed. Cylinders as will just make the lists too large at that point just allow all regular polygons.
