In geometry, an icosahedron is a polyhedron with 20 faces. The name comes from Ancient Greek εἴκοσι (eíkosi) 'twenty', and ἕδρα (hédra) 'seat'. The plural can be either "icosahedra" (/-drə/) or "icosahedrons". There are infinitely many non-similar shapes of icosahedra, some of them being more symmetrical than others. … See more There are two objects, one convex and one nonconvex, that can both be called regular icosahedra. Each has 30 edges and 20 equilateral triangle faces with five meeting at each of its twelve vertices. Both have icosahedral symmetry. … See more A regular icosahedron can be distorted or marked up as a lower pyritohedral symmetry, and is called a snub octahedron, snub … See more • 600-cell • Icosoku See more Stellation is the process of extending the faces or edges of a polyhedron until they meet to form a new polyhedron. It is done symmetrically so that the resulting figure retains the overall … See more Rhombic icosahedron The rhombic icosahedron is a zonohedron made up of 20 congruent rhombs. It can be derived from the rhombic triacontahedron by removing 10 middle faces. Even though all the faces are congruent, the … See more WebThe term -conta-refers to a group of ten, so a hexecontahedron has 60 sides. Modifiers may describe the shape of the faces, to disambiguate between two polyhedra with the same number of faces. For example, a rhombic dodecahedron has 12 rhombus-shaped faces. A pentagonal icositetrahedron has 24 (i.e., 20+4) five-sided
