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}.

Cartesian coordinates

Cartesian coordinates for the vertices of a great stellated truncated dodecahedron are all the even permutations of

(0, ±τ, ±(2−1/τ))
(±τ, ±1/τ, ±2/τ)
(±1/τ2, ±1/τ, ±2)

where τ = (1+√5)/2 is the golden ratio (sometimes written φ).
