Name Waterman polyhedron number 6 wrt. face-centered cubic lattice A3 centered at a lattice point
 
    ©
Face vector 32, 72, 42

The unit here was chosen as the small root of A3.

By the very definition of Waterman polyhedra, not necessarily all vertices are on the same sphere. In here the 8 maximal ones (gray vertices) have a circumradius of sqrt(6) = 2.449490, while the other 24 vertices (green ones) only are at an radius of sqrt(5) = 2.236068.

The rhombs {(r,R)2} have vertex angles r = arccos(1/3) = 70.528779° resp. R = arccos(-1/3) = 109.471221°. Esp. rr : RR = sqrt(2).
