Talk:Chamfered dodecahedron

Alternation?
Glad for additions, but this seems wrong:
 * The truncated rhombic triacontahedron is more properly an alternation of the rhombic triacontahedron, rather than a uniform truncation of it.

An alternated polyhedron will have half the vertices. It could be most accurately called a alternated truncation, but not an alternation. Tom Ruen 00:21, 30 August 2007 (UTC)


 * You're right — I misread the alternation article. Thanks for the correction. So there is no specific name for a truncation that removes alternating vertices but in which the new faces remain nonadjacent from each other? While we're discussing this, is there a name or article for the form of truncation in which one replaces each edge of a polyhedron by a new facet? Sort of like cantellation but without the new facets on the vertices. It seems this polyhedron could be formed in that way from a regular dodecahedron. —David Eppstein 00:36, 30 August 2007 (UTC)


 * The Conway polyhedron notation allows a truncation order, and George W. Hart's VRML generator has this operation as t5daD by only truncating order-5 vertices. It isn't complete since it can't work on other polyhedrons, for example, an alternate truncated cube.


 * You're right on an (unnamed) edge truncation operation here which would make faces smaller like cantellate and replace edges by hexagons. The 30 hexagons here come from the 30 edges of a dodecahedron! Tom Ruen 01:32, 30 August 2007 (UTC)
