Dihedral angles 

The rhombs {(r,R)^{2}} have vertex angles r = 60° resp. R = 120°. Esp. rr : RR = sqrt(3). – Alternatively the rhombs could be devided into pairs of coplanar regular triangles, but then asking for an additional edge each. – Accordingly, when filling the rhombic dimples halfway with peppies, this polyhedron could be transformed into a nonintersectingly concave polyhedron xfo3foo5oxf&#zx with regular polygons only.
This concave polyhedron also allows for an expansion (xfoa3fooo5xuFx&#zx), which then still is nonintersectingly concave, but where all faces then would be regular polygons. Thereby the rhombs will become hexagons.
