You can read a bit about the companyâs history in this article, but I canât point you to the companyâs web site for the simple reason that it doesnât have one. Yes, as amazing as this is, here in mid-2009 Arca Swiss lacks a web site, one of the few companies of any size in the photographic industry without one.
A pyritohedron is a dodecahedron with pyritohedral (T h) symmetry. Like the regular dodecahedron, it has twelve identical pentagonal faces, with three meeting in each of the 20 vertices. However, the pentagons are not constrained to be regular, and the underlying atomic arrangement has no true fivefold symmetry axes.
Best Answer: A dodecahedron has twelve faces, twenty vertices, and thirty sides. Strictly speaking, that diagram is not a dodecahedron because it is two-dimensional. It is the net of a dodecahedron. When folded up it will have 12 faces, 20 vertices and 30 edges. Note that these figures must fit the formula F + V = E + 2 which applies to all polyhedra. 10 faces, 38 sides and 25 vertices. In geometry, a dodecahedron (Greek Î´ÏÎ´ÎµÎºÎ¬ÎµÎ´ÏÎ¿Î½, from Î´ÏÎ´ÎµÎºÎ± 'twelve' + ÎµÎ´ÏÎ¿Î½ 'base', 'seat' or 'face') is any polyhedron with twelve faces, but usually a regular dodecahedron is meant: a Platonic solid.
