 ©
Vertex figure [r5], [r,h,3,h], [R2,H]
General of army (is itself convex)
Colonel of regiment (is itself locally convex)
Face vector 132, 240, 110

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) = 1.414214.
The hexagons {(h,h,H)2} have vertex angles h = arccos(-sqrt[(3-sqrt(5))/6]) = 110.905157° resp. H = arccos[-sqrt(5)/3] = 138.189685°.

This polyhedron is just the Stott expansion of the rhombic enneacontahedron wrt. its icosahedral vertices.

All a, b, c, and d edges, provided in the below description, only qualify as pseudo edges wrt. the full polyhedron.
