Acronym ... Name hyperbolic order 3 tritetragonal tiling ` ©   ` Circumradius sqrt[-3 sqrt(2)/8] = 0.728238 i Vertex figure [(3,4)3] Confer related hyperbolic polytopes: pex-o3o4o3*a   pabex-o3o4o3*a   pac-o3o4x3*a   general polytopal classes: partial Stott expansions Externallinks

This tiling allows for a consistent 4-coloring of the triangles. This then could give rise for a series of partial Stott contractions, each reducing one set of triangles piecewise into points.
