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 8 maximal ones (polar vertices) have a circumradius of sqrt(3/2) = 1.224745, while the other 8 vertices (tropical ones) only are at an radius of sqrt(5)/2 = 1.118034.
The irregular hexagons {(h,H,H)2} have vertex angles h = arccos(-1/3) = 109.471221° resp. H = arccos[-1/sqrt(3)] = 125.264390°.
