Dodecahedron
In geometry, a dodecahedron (Greek δωδεκάεδρον, from δώδεκα dōdeka "twelve" + ἕδρα hédra "base", "seat" or "face") is any polyhedron with twelve flat faces. The most familiar dodecahedron is the regular dodecahedron, which is a Platonic solid. There are also three regular star dodecahedra, which are constructed as stellations of the convex form. All of these have icosahedral symmetry, order 120.
The pyritohedron is an irregular pentagonal dodecahedron, having the same topology as the regular one but pyritohedral symmetry while the tetartoid has tetrahedral symmetry. The rhombic dodecahedron, seen as a limiting case of the pyritohedron has octahedral symmetry. The elongated dodecahedron and trapezo-rhombic dodecahedron variations, along with the rhombic dodecahedra are space-filling. There are a large number of other dodecahedra.
Pentagonal dodecahedron
The convex regular dodecahedron is one of the five regular Platonic solids and can be represented by its Schläfli symbol {5, 3}.

Dodecahedron
by: Anubis GateOut here at the timeline at lightspeed I travel although my thinking's barely moving
I'm recharging my senses
Awaiting tomorrow
One more place in time
Just a flash and I'll be back on earth again
Building dreams for free men
Just a flash and I'll be part of life again
Anywhen
Out here at the timeline
The dodecahedron retains the history we're living
A second home for the detached with room for reflection
Out of space and time
Just a flash and I'll be back on earth again
Building dreams for free men
Just a flash and I'll be part of life again
Anywhen
I penetrate the aerosphere
My destination's drawing near
Through halls of myth and dreamy light
The noise, the sand, the building site
Just a flash and I'll be back on earth again
Building dreams for free men
Just a flash and I'll be part of life again
