    Default Are there any new platonic solids in non-euclidean space

    I know thay in the 2 dimensional elliptic plane there are two additional regular polygons, the digon/lune, and the monogon/henagon.

    Does this sort of effect extend into 3 dimensional elliptic space? Is there a regular elliptic polyhedron with fewer faces than the tetrahedron?

    EDIT:
    On further thought, it seems obvious that there must be a single-faced regular polyhedron in elliptic space that's just a flat plane extended until it contacts itself. But are there 2 faced or three faced regular polyhedra?

    I found this relatively quickly:

    I find this topic interesting, so I might look further later.
