600-cell (cell-first)
600-cell
This is the cell-first (tetrahedron-first) orthographic projection of the 600-cell into 3-space. It is one of the six convex regular polychora (4-dimensional version of the Platonic solids). It contains 600 tetrahedral cells, 1200 equilateral triangles, 720 edges, and 120 vertices with an icosahedral vertex figure.
