obo3coc&#xt (c = q/2 = 1/sqrt(2))   obo3coc&#xt (c = b/2 = sqrt(2/3))   obo3coc&#xt (c = b/2 = sqrt[(5+sqrt(5))/10])  

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


Incidence matrix according to Dynkin symbol

obo3coc&#xt   → both heights = sqrt(2/3) = 0.816497
                b = 2h/3 = 2/sqrt(3) = 1.154701 (occurs just as small diagonal of rhomb of rad)
                c = h/3 = 1/sqrt(3) = 0.577350 (occurs as edge size)
