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.
In a regular dodecagon, each side of the figure has equal length, and each of its interior angles shares the same measurement of 150 degrees. The sum of all of these angles is 1800. To compute a close approximation of the area, we can multiply 11.2 times the square of length of any of the sides since they are all equal.
