Regular polytope facts for kids
In mathematics, a regular polytope is the generalisation of the regular polygon. Like other polytopes it may have any natural number of dimensions. For example, a two-dimensional regular polytope is a regular polygon, and a three-dimensional regular polytope is a regular polyhedron. Like with the regular polygon, there are certain kinds of symmetries. Regular polytopes have regular facets (faces to speak from the 3D viewpoint), and their vertex figures are regular.
The simplest of the six convex regular 4-polytopes are the pentachoron and tesseract.

A 3D projection of a rotating tesseract. This tesseract is initially oriented so that all edges are parallel to one of the four coordinate space axes. The rotation takes place in the xw plane.
