User:Double sharp/Naming polygons

My usual system (the one I would use when RS is not an issue, i.e. outside WP).

I plead guilty to the inconsistent transliteration as kappa as both k and c in the same word. In my defense, you don't see dekagon or triscaidecagon (although I did once see heccaidecahedron). My main excuse is that I wanted to keep names that are used, and build around them. Hence I keep icosikaitetragon (tens before units), though the original Ancient Greek would have it the other way around. I also thus have to keep hexakaidecagon, which is more common than the more etymologically correct hekkaidecagon: the same applies for my thus having to reject my beloved hebdomecontagon, ogdoecontagon, and enenecontagon (which are too far from expectation, so don't get used, while pentecontagon and hexecontagon survive). I keep -kai- for all save 11 and 12, as that is what Ancient Greek does.
