Acronym giddird Name great dirhombidodecahedron,compound of 12 stip ` © ` Circumradius sqrt[(15-2 sqrt(5))/20] = 0.725530 Vertex figure 2[42,5/2] General of army srid Colonel of regiment (itself, even so not being locally convex) Externallinks

Vertices coincide by pairs. So either they can be considered separately (type A) or are identified (type B). Finally, instead of considering individual stip, it can likewise be seen as a compound of 2 (different handed) gikrid (type C).
