The Hexagonal Prism
The hexagonal prism is a 3D uniform polyhedron bounded by 2 hexagonal faces and 6 squares. It has 18 edges and 12 vertices. It is the extrusion of the hexagon into 3D.
In order to be able to identify the hexagonal prism in various projections of 4D objects, it is useful to know how it appears from various viewpoints. The following are some of the commonly-encountered views:
Hexagon-centered parallel projection.
Parallel projection centered on a vertical edge.
Square-centered parallel projection.
Vertex-centered parallel projection.
The Cartesian coordinates of the hexagonal prism, centered on the origin and having edge length 2, are:
- (±√3, ±1, ±1)
- (0, ±2, ±1)
The hexagonal prism occurs as cells in the following 4D uniform polytopes:
