  • White

    White nylon plastic with a matte finish and slight grainy feel.


There are six regular convex polytopes in 4D, which are analogous to the five Platonic solids in 3D. This is the first, the pentachoron or hyperpyramid, in a vertex-first projection. It has 5 tetrahedral cells, and like the tetrahedron is its own dual.

In every dimension there's one polytope like this: all triangles, self-dual, analogous to the tetrahedron. As a group they're called simplexes, so this is the 4-simplex.
