Acronym birachach
Name hyperbolic birectified alternated order-6 cubic honeycomb,
hyperbolic runcic order-6 cubic honeycomb
Circumradius sqrt[-(1+sqrt(3))/2] = 1.168771 i

This non-compact hyperbolic tesselation uses both the euclidean tilings hexat and rothat in the sense of infinite horohedra as some of its cells.
