Hexahemioctacron
Encyclopedia
In geometry
, the hexahemioctacron is the dual of the cubohemioctahedron
, and is one of nine dual hemipolyhedra. It appears visually indistinct from the octahemioctacron
.
Since the cubohemioctahedron has four hexagonal faces
passing through the model center, The hexahemioctacron has four vertices
at infinity. In Magnus Wenninger
's Dual Models, they are represented with intersecting infinite prisms
passing through the model center, cut off at a certain point that is convenient for the maker.

Geometry arose as the field of knowledge dealing with spatial relationships. Geometry was one of the two fields of pre-modern mathematics, the other being the study of numbers ....

Cubohemioctahedron
In geometry, the cubohemioctahedron is a nonconvex uniform polyhedron, indexed as U15. Its vertex figure is a crossed quadrilateral.A nonconvex polyhedron has intersecting faces which do not represent new edges or faces...

Face (geometry)
In geometry, a face of a polyhedron is any of the polygons that make up its boundaries. For example, any of the squares that bound a cube is a face of the cube...

Prism (geometry)
In geometry, a prism is a polyhedron with an n-sided polygonal base, a translated copy , and n other faces joining corresponding sides of the two bases. All cross-sections parallel to the base faces are the same. Prisms are named for their base, so a prism with a pentagonal base is called a...
