User:Tomruen/Stellations of 16-cell

In 4-dimensional geometry, a stellation of a 16-cell is a 4-polytope constructed as volumes between hyperplane of the facets of a regular 16-cell.

Vertices
There are 4 sets of vertices as intersections of 4 hyperplanes:

1-regions
These 4 sets define 7 1-regions (line segments):

2-regions
The 4 sets define 8 types of 2-regions (triangles|

3-regions
The 4 sets define 7 types of 3-regions (polyhedra):

layers
There are 5 layers (polychora):

Stellations
There are 6 stellated forms:
