WebJun 5, 2024 · The sphere inscribed polyhedron should be convex too. Also, preferrably no two distinct faces of the polyhedron should be coplanar, otherwise they can be combined to a single face. In this sense, the Triakis tetrahedron is indeed a counter-example to my question. There are inscribed polyhedra equivalent to it, but they are either not convex or ...
