What is a dodecadodecahedron?
Jump to navigation Jump to search. In geometry, the dodecadodecahedron is a nonconvex uniform polyhedron, indexed as U 36. It is the rectification of the great dodecahedron (and that of its dual, the small stellated dodecahedron). It was discovered independently by Hess (1878), Badoureau (1881) and Pitsch (1882).
What is a dodecahedron with an edge length of one unit?
A dodecahedron with an edge length of one unit has the properties: The regular dodecahedron has two special orthogonal projections, centered, on vertices and pentagonal faces, correspond to the A 2 and H 2 Coxeter planes .
What is the rectified dodecahedron?
It is the rectification of the great dodecahedron (and that of its dual, the small stellated dodecahedron ). It was discovered independently by Hess ( 1878 ), Badoureau ( 1881) and Pitsch ( 1882 ). The edges of this model form 10 central hexagons, and these, projected onto a sphere, become 10 great circles.
How many nets does a dodecahedron have?
If the original regular dodecahedron has edge length 1, its dual icosahedron has edge length ϕ. If the five Platonic solids are built with same volume, the regular dodecahedron has the shortest edges. It has 43,380 nets. The map-coloring number of a regular dodecahedron’s faces is 4.
