Regular Skew Polyhedron
In geometry, the regular skew polyhedra are generalizations to the set of regular polyhedron which include the possibility of nonplanar faces or vertex figures.
These polyhedra have two forms: infinite polyhedra that span 3-space, and finite polyhedra that close into 4-space.
