Great dodecahedron. While its faces are regular pentagons its vertex figures are regular pentagram stars. 4 days ago · The great dodecahedron has 12 faces, 12 vertices and 30 edges and its Euler characteristic F E + V = 12 30 + 12 = 6 shows that it is an orientable surface of genus 4. The story follows a bored young boy named Milo who unexpectedly receives a magic tollbooth that transports him to the once prosperous, but now troubled, Kingdom of Wisdom. The great dodecahedron stands as a testament to the infinite creativity possible within mathematical constraints. org/wiki/Great_dodecahedron The great dodecahedron can also be obtained by stellation: starting with the small stellated dodecahedron, we can extend the faces to obtain this new solid. 1954), and Har'El index 40 (Har'El 1993). Every Day new 3D Models from all over the World. All are reflexible, and these stellations are identical using either the fully supported or Miller's rules criterion (Webb). The Great Dodecahedron A non-convex polyhedron bounded by twelve intersecting pentagonal faces. Mar 11, 2026 · The great dodecahedron is the Kepler-Poinsot polyhedron whose dual is the small stellated dodecahedron.

This shape The great dodecahedron stands as a testament to the infinite creativity possible within mathematical constraints. Great dodecahedron 3D model of a great dodecahedron In geometry, the great dodecahedron is one of four Kepler–Poinsot polyhedra. In geometry, the small stellapentakis dodecahedron is a nonconvex isohedral polyhedron. ). In geometry, the great dodecahedron is one of four Kepler–Poinsot polyhedra. It is composed of 12 pentagonal faces (six pairs of parallel pentagons), intersecting each other making a pentagrammic path, with five pentagons meeting at each vertex. 5. It is composed of 12 pentagonal faces, intersecting each other making a pentagrammic path, with five pentagons meeting at each vertex. By extending the familiar dodecahedron into star form, we discover a universe of geometric possibilities that challenge our preconceptions about shape and space. It is also uniform polyhedron with Maeder index 35 (Maeder 1997), Wenninger index 21 (Wenninger 1989), Coxeter index 44 (Coxeter et al. It is composed of 12 pentagonal faces (six pairs of parallel pentagons), with five pentagons meeting at each vertex, intersecting each other making a pentagrammic path. 35 and 38-40; Coxeter 1999, p. The original dodecahedron, its 12 facial planes . 14; Webb). The Phantom Tollbooth is a children's fantasy novel written by Norton Juster, with illustrations by Jules Feiffer, first published in 1961. The truncated great stellated dodecahedron is a degenerate polyhedron, with 20 triangular faces from the truncated vertices, and 12 (hidden) pentagonal faces as truncations of the original pentagram faces, the latter forming a great dodecahedron inscribed within and sharing the edges of the icosahedron. It is one of four nonconvex regular polyhedra. In geometry, a truncated icosidodecahedron, rhombitruncated icosidodecahedron, great rhombicosidodecahedron, omnitruncated dodecahedron or omnitruncated icosahedron is an Archimedean solid, one of thirteen convex, isogonal, non-prismatic solids constructed by two or more types of regular polygon faces.

Along with a dog named Tock and the Humbug, Milo goes on a quest to the Castle in This is the great dodecahedron in solid form: For an interactive model of it, see the Interactive Models page. wikipedia. It has twelve ' 5 / 2 ' star vertices. It has the following properties: Vertex figure: (5. The great dodecahedron is one of the 4 concave regular polyhedra. It is the dual of the truncated great dodecahedron. Another way of saying this is to call the great dodecahedron the second stellation of the dodecahedron. Its Schläfli symbol is {5,5/2} and its Wythoff symbol is 5/2|25. These self intersecting poly-hedral surfaces share many symmetry properties with Platonic solids (like flag transitivity, constant lengths of Petrie polygons, etc. The great dodecahedron is one of the four Kepler-Poinsot Star Polyhedra, and is also the second stellation of the dodecahedron.
