Acronym ... Name edge faceting raded-1-10-5-5 Circumradius sqrt(7)/2 = 1.322876 Vertex figure [4,5,6], [4,5,4,5/2], [4,6,4/3,6/5]/0 Confer faceting of: raded   blends: 12 raded-1-10-5-5 Externallinks

It should be noted here, that the squares are situated fully within the mirror planes underneath the edges of doe. Accordingly there could be constructed an (centrally hollow) external blend from 12 such self-intersecting polyhedra (12 raded-1-10-5-5), blending out half of their squares, cf. the picture at the right.
