Default Platonic solids and the Golden ratio (r)

As an erstwhile 3D-engine programmer (among other things)
I read a beautiful article about simple starting points for the
vertices of the five regular solids.

Before my video(visio?)spatial ability goes completely bonkers
let me try to remember them:

(1,1,1), (1,-1,-1), (-1,1,-1), (-1,-1,1) tetrahedron

(+/-1,+/-1,+/-1) cube

(+/-1,0,0) etc octahedron

(+/-r,+/-1,0) (permute cyclicly) icosohedron

HELP!
