Acronym tigiddip Name truncated-great-dodecahedron prism Circumradius sqrt[(19+5 sqrt(5))/8] = 1.942303 Colonel of regiment (is itself locally convex – no other uniform polyhedral members) Dihedral angles at {4} between dip and stip:   arccos(-1/sqrt(5)) = 116.565051° at {10} between dip and tigid:   90° at {5/2} between stip and tigid:   90° at {4} between dip and dip:   arccos(1/sqrt(5)) = 63.434949° Externallinks

As abstract polytope tigiddip is isomorphic to quit sissiddip, thereby replacing pentagrams by pentagons and decagons by decagrams, resp replacing tigid by quit sissid, stip by pip, and dip by stiddip.
