- A
dihedron (pl. dihedra) is a type of polyhedron, made of two
polygon faces which share the same set of n edges. In three-dimensional
Euclidean space,...

constructed as a
vertex on a
great circle (equator). This
forms a
dihedron, {1,2}, with two
hemispherical monogonal faces which share one 360° edge...

which is both a
hosohedron and a
