This non-compact hyperbolic tesselation uses the euclidean tiling trat in the sense of an infinite horohedron as cell.

It can be derived as further partial Stott contraction of pac-x4o3x3o3*b, contracting the lacing heights of an other one of the trip classes (e.g. the one marked "v" below).

A last contraction, e.g. of the "g" edges, then results then in o4o3x3o3*b. The other way round, it thus could be said to be its partial expansion.
