How can I find the normals of a Dodecahedron in rational numbers?

[QUOTE="TheDestroyer, post: 4050964, member: 2938"] Hello guys, I need the normals of a Dodecahedron (fully symmetric 12 facets' polyhedron) given in rational numbers. I got tired searching the internet for that, so I expect something like: {-Sqrt[1 + 2/Sqrt[5]], 0, 1/2 Sqrt[1/10 (5 - Sqrt[5])]]} I tried Mathematica, but it gives 20 Faces for a Dodecahedron! Apparently there are repeated facets and it uses some systematic way to draw the Dodecahedron. The code I use to get the Facets in Mathematica is: PolyhedronData["Dodecahedron", "Faces"] Any help is highly appreciated. Thanks. [/QUOTE]
