- In
elementary geometry, a
polytope is a
geometric object with flat
sides (faces).
Polytopes are the

polyhedra to any...

polytopes were
discovered by the
Swiss mathematician Ludwig Schläfli
before 1853. The two-dimensional
analogue of a 4-
polytope is a polygon...

There are six
convex and ten star
regular 4-
polytopes,
giving a
total of sixteen. The
convex regular 4-
polytopes were
first described by the

there are 39
uniform polytopes with E6 symmetry. The two

These polytopes are part of a

Coxeter lists a few of
these in his book
Regular Polytopes.
