 Archimedean Polyhedra
Except for the truncated tetrahedron, lower right, all the Archimedean polyhedra are modifications of the cube-octahedron pair or the dodecahedron-icosahedron pair.
The tetrahedron and truncated tetrahedron are shown in the last pair.
For example, in the top row we see a truncated tetrahedron with vertices 3.6.6 (n=3), a truncated cube with 3.8.8 (n=4), a truncated dodecahedron with 3.10.10 (n=5).

  Index: Platonic and Archimedean Solids (69-79)
The five regular convex polyhedra, or Platonic solids, are the tetrahedron, cube, octahedron, dodecahedron, icosahedron (75 - 79), with 4, 6, 8, 12, and 20 faces, respectively.
Similarly, the dodecahedron and the icosahedron are duals of each other, and the tetrahedron is its own dual.
Thus we obtain the truncated cube (69), the truncated tetrahedron (70), the truncated octahedron (74).

 Truncated rhombic dodecahedron Information
The truncated rhombic dodecahedron is a convex polyhedron constructed from the rhombic dodecahedron by truncated the 6 (order 4) vertices.
Note that this name is ambiguous since only 6 vertices were truncated, and different polyhedra can be generated by truncating the other 8 vertices, or all 14 vertices of the original rhombic dodecahedron.
Truncated rhombic dodecahedron is the Minkowski sum of a rhombic dodecahedron and a cube of side length 1 when eight vertices of the rhombic dodecahedron are at

 The Archimedean Solids
The three solids this process will produce are the dodecahedron, a Platonic solid, and the two Archimedean solids known as the truncated dodecahedron and the icosidodecahedron.
Another shape, which could be obtained from a dodecahedron, is easier to obtain by this method by trimming the corners of an icosahedron, thus creating little pentagonal faces at each corner, and changing the triangular faces to hexagons.
If we were to truncate the corners more deeply, so as to change the existing faces to triangles pointed the other way instead of hexagons, we would not obtain an Archimedean solid, but instead another Platonic solid, the octahedron.

 Dodecahedron Day: Nets for Models   (Site not responding. Last check: )
A geodesic dodecahedron may be formed by projecting a dodecahedron onto a sphere, and then subdividing each pentagon into five congruent spherical triangles.
For this geodesic version of the snub dodecahedron, the triangles are kept intact, while the pentagons are subdivided into five isosceles spherical triangles.
Since subdividing the spherical triangles of the truncated dodecahedron into six subtriangles would make them too small, James decided to subdivide them into only three smaller triangles.

 Truncated Dodecahedron
The truncated dodecahedron is one of the thirteen Archimedean solids.
It is generated by truncating the vertices of a dodecahedron such, that the faces of the dodecahedron are cut to regular dakagons.

 Truncated_dodecahedron - The Wordbook Encyclopedia
In geometry, the truncated dodecahedron is an Archimedean solid.
This polyhedron can be formed from a dodecahedron by truncating (cutting off) the corners so the pentagon faces become decagons and the corners become triangles.
The following Cartesian coordinates define the vertices of a truncated dodecahedron centered at the origin:

 Polyhedra
One of these solids, the truncated tetrahedron, can be inscribed in a regular tetrahedron.
The next six can be inscribed in either a cube or an octahedron, and the last six in either a dodecahedron or an icosahedron.
The 'truncated' solids are so called because each can be constructed by cutting off the corners of some other solid, but the truncated cuboctahedron and icosidodecahedron require a distortion in addition to convert rectangles into squares.

 Truncated Dodecahedron
If you slice off a vertex of a dodecahedron, but not too deep, the slice leaves a new, triangular face.
If you slice them all off to just the right depth so that the triangular faces meet each other halfway along the original edges (which thereby all disappear), you get this.
If you slice them all off to just the right depth so that the pentagonal faces meet each other halfway along the original edges (which thereby all disappear), you get this.
