WebHere is the compound of great stellated dodecahedron, {5/2, 3}, and its dual, the great icosahedron, {3, 5/2}. Similarly, the small stellated dodecahedron, {5/2, 5}, and its dual, the great dodecahedron, {5, 5/2}, can be combined into this compound. But all you see from the outside is the former; you have to go inside it to see the latter. WebThe dodecahedron is a Platonic solid, which has all its faces with a pentagonal shape. A dodecahedron consists of 12 faces, 30 edges, and 20 vertices. Three pentagonal faces meet at each vertex. An interesting …
