The nonregular hexagons {(h,H,H)^{2}} are diagonally elongated squares. Its vertex angles are h = 90° resp. H = 135°.
Chamfering (or edgeonly beveling – here being applied to the tet) flatens the former edges into new (nonregular hexagonal) faces.
There is a deeper, terminal chamfering of the tet too, which then reduces the original faces to nothing. Then the hexagons will become squares and the total figure becomes the cube. – When considering the below provided tegum sum Dynkin symbol, it becomes obvious that this figure also can be seen as a Stott expansion of the cube.
