Pyritohedron

Description

Dodecahedral pyrite, built from trimming a 6x6x6 supercell at the {210} family of planes at points [1,.5,.5] and [0,.5,.5]. Drawn lines on edges of pentagonal faces terminate at points [x,y,z] where x,y,and z are multiples of 1/6 of the 6x6x6 lattice cell length, so they do not always appear exactly at atoms. The pyritohedron is not a true dodecahedron because the edges of each face are not equal in length.
