The nonregular hexahedra {(h,H,H)^{2}} have vertex angles h = arccos(1/3) = 109.471221° resp. H = arccos[1/sqrt(3)] = 125.264390°.
Octahedral truncation applies to the octahedral vertices (vertex inscribed oct) only. Wrt. the rad this produces new square faces there. These are then face planes of a cutting cube. – The above transition shows a dynamical mutual scaling of cube and rad. The chamfered cube then is the instance, where all edges happen to have the same length.
Chamfering (or edgeonly beveling – here being applied to the cube) flatens the former edges into new (nonregular hexagonal) faces.
There is a deeper, terminal chamfering of the cube too, which then reduces the original faces to nothing. Then the hexagons will become rhombs and the total figure becomes the rad. – 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 rad.
