Acronym ... Name 2srico+144{8}+576{3} (?) Circumradius sqrt[4+2 sqrt(2)] = 2.613126 General of army srico Colonel of regiment srico Confer Grünbaumian relatives: 2srico   2srico+192trip

This is a scaliform variant of a faceting of a Grünbaumian double-cover of the prismatorhombated icositetrachoron (prico). It comes out to be edge-inscribable to the small rhombated icositetrachoron (srico). The additional 144 octagons are those inscribed into the former small rhombicuboctahedra (sirco), the additional 576 triangles are used to produce a octuple coincidence of the former sirco-sirco triangles.
