1) Polyhedron 1) Prismoid 
== Prismatoid families == Families of prismatoids include: == Higher dimensions == In general a polytope is prismatoidal if its vertices exist in two hyperplanes. For example in 4-dimension, two polyhedra can be placed in 2 parallel 3-spaces, and connected with polyhedral sides. A tetrahedral-cuboctahedral cupola. ...
