Compare higher degree rectifications.
What are higher degree cantellations?
I didn't find any definition on internet, at least no operational description.
You can find constructions by coordinates for "bicantellated 7-cube" or "tricantellated 8-simplex", so please don't tell me that the term is "not useful" or meaningless.
From the term itself, I can imagine many possible meaning of "bicantellated". What is then the correct notion of higher degree cantellations?
