11. The original dodecahedron cells are cantitruncated into great rhombicosidodecahedron cells. 12. Like the snub dodecahedron , it has chiral icosahedral symmetry. 13. The Bilinski dodecahedron has 4 belts of 6 coparallel edges. 14. Dodeca is a contraction for dodecahedron , a solid object with 12 faces. 15. However, neither the regular icosahedron nor the regular dodecahedron are amongst them. 16. Joining the twenty vertices would form a regular dodecahedron . 17. Hamilton himself used a flattened dodecahedron as the basis for his instructional game. 18. The rhombic dodecahedron also appears in the unit cells of diamond and diamondoids. 19. The remaining 12 octahedral cells project onto the faces of the rhombic dodecahedron . 20. Truncating edges down to points produces the dodecadodecahedron as a rectified great dodecahedron .
