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).
