Acronym scuffi Name semicupolaically faceted icosahedron Circumradius sqrt[(5+sqrt(5))/8] = 0.951057 Vertex figures [3,3,5,3/2,5], [3,5,3/2,5/4]/0, [3,3,5] Dihedral angles (at margins) between {3} and {3}:   arccos(-sqrt(5)/3) = 138.189685° between {3} and {5}:   arccos[(5+2 sqrt(5))/15] = 37.377368° Confer uniform relative: gad   ike   faceting of: ike   blend-component: peppy

As abstract polytope scuffi is isomorphic to scufgi, thereby replacing pentagons by pentagrams.

This polyhedron either can be considered as a faceting of ike or else could be constructed as a blend from 3 copies of peppy, when taken all coincident with one single triangle, but mutually in rotated fashion.
