Edge-only bevelling (here being applied to the hex) flatens the former edges into new elongated rhombohedral cells (ebauco, abx ooc4odo&#zx) while the former regular polyhedral cells (here: tets) get rasped down into chamfered versions thereof (bx3oo3oc&#zx). – It should be added here, that only the axial 4fold symmetry of the former edges makes it possible to get all edges in this edge-bevelling to the same size. For any other symmetry the rhombs at the tips of those new cells would deform into kites.

The non-regular hexagons {(h,H,H)2} are diagonally elongated squares. Their vertex angles are h = 90° resp. H = 135°. The rhombs {(r,R)2} are just a coplanar pair of regular triangles. Their vertex angles are r = 60° resp. R = 120°. The below mentioned node symbols a, b, c, and d all represent pseudo edges only.

Octa-diminishing this polychoron at the tips of the ebauco cells results in poxrico.

There is a deeper, terminal edge-bevelling of the hex too, which then reduces the original triangles to nothing. Then the hexagons will become rhombs and the total figure becomes the a'b'o3ooo3ooc4odo&#zx (with a' = a-x, b' = b-x). – When considering the below provided tegum sum Dynkin symbol, it becomes obvious that this figure here also can be seen as a Stott expansion of that a'b'o3ooo3ooc4odo&#zx.
