Circumradius sqrt[1-sqrt(2)]/2 = 0.321797 i

uniform relative:
o8o4x *b3x  

As the order 8 square tiling within o8o4x *b3x were 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 there allow for an attaching layer of trips. The magic then is, 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 obtain this still uniform lamina-truncate, built from sircoes and trips only.
