A polyon is a name coined by Holomanga to describe 0-dimensional polytopes to match the naming system of other polytopes, such as polytelon and polychoron.
List of Polya Edit
The name is a combination of poly- and -on, with no letters in between. It was created by extrapolating the SI-based system (e.g. polypeton, polyexon) backwards to 0 dimensions, which would be no prefix, and by analogy to dyad/ditelon/monad.
