Acronym quitdiddip Name quasitruncated-dodecadodecahedron prism Circumradius sqrt(3) = 1.732051 Colonel of regiment (is itself locally convex – no other uniform polyhedral members) Dihedral angles at {4} between cube and stiddip:   arccos(-sqrt[(5+sqrt(5))/10]) = 148.282526° at {4} between cube and quitdid:   90° at {10} between dip and quitdid:   90° at {10/3} between quitdid and stiddip:   90° at {4} between dip and stiddip:   arccos(1/sqrt(5)) = 63.434949° at {4} between cube and dip:   arccos(sqrt[(5-sqrt(5))/10]) = 58.282526° Externallinks

As abstract polytope quitdiddip is automorph, thereby interchanging the roles of decagons and decagrams, resp. those of dip and stiddip.
