Description1 22 E6 to 3D H3 symmetry concentric hulls.png
English: The E6 1_22 polytope is projected to 3D using 3 rows of the E8 to H4 folding matrix giving H3 symmetry. The vertices are sorted and tallied by their 3D norm. Generating the increasingly transparent hull of each set of tallied norms shows 1 icosahedron, 1 dodecahedron and 2 irregular 20-vertex polytope for a total of 72 vertices.
