Great stellated truncated dodecahedron
In geometry, the great stellated truncated dodecahedron or quasitruncated great stellated dodecahedron is a nonconvex uniform polyhedron, indexed as U66. It is given a Schläfli symbol t0,1{5/3,3}.
It shares its vertex arrangement with three other uniform polyhedra: the small icosicosidodecahedron, the small ditrigonal dodecicosidodecahedron, and the small dodecicosahedron:
Cartesian coordinates for the vertices of a great stellated truncated dodecahedron are all the even permutations of
where τ = (1+√5)/2 is the golden ratio (sometimes written φ).
