Acronym ... Name hyperbolic o8o4x *b3x tesselation Circumradius sqrt[1-sqrt(2)]/2 = 0.321797 i Confer uniform relative: lamina-trunc( o8o4x *b3x )

This hypercompact hyperbolic tesselation uses the order 8 triangle tiling and the order 8 square tiling in the sense of infinite bollohedra as some of its cell types.

As the order 8 square tiling here are hemi-choral (have same curvature resp. intersect the sphere of infinity orthogonally) those could be replaced by mirror images of the remainder each. Further the order 8 triangle tiling allow for an attaching layer of trips. The magic then would be, that the bollo-surface through their center points again happens to be hemi-choral, thus there too a second type of mirror can be placed. Accordingly we thus would produce the lamina-trunc( o8o4x *b3x ), built from sircoes and trips only.
