general polytopal classes:
partial Stott expansions  

Both, trat and the tri-hexagonal rhombic tiling (derived from the former by combining 2 triangles each) could be considered as a vertex overlay of hexat plus 3 shifted copies of trats with edge size 3 (see there). This decomposition allows for a 3-step partial Stott expansion of the latter running then through rhombic uBxx3xoAo3xooA3*a&#zx and this tiling towards a pure hexat (A = 3x, B = 4x).
