heptahedron

A heptahedron is a polyhedron with seven faces.

According to the Steinitz classification of f-vectors of 3-polytopes and the Euler polyhedron formula together imply that a convex heptahedron will have one of the followng f-vectors:

• $(6,11,7)$

• $(7,12,7)$

• $(8,13,7)$

• $(9,14,7)$

• $(10,15,7)$
