Name | Waterman polyhedron number 8 wrt. body-centered cubic lattice C3* centered at a lattice point |
Face vector | 48, 96, 50 |
The unit here was chosen as the cubic edge of C3*.
By the very definition of Waterman polyhedra, not necessarily all vertices are on the same sphere. In here the 24 maximal ones (green vertices) have a circumradius of sqrt(5) = 2.236068, while the other 24 vertices (blue ones) only are at an radius of sqrt(19)/2 = 2.179449.
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).
