For the same reason I don't use my own pet name for it---I do have short names for these things, y'know!
What's your pet name for it?
I like "luchna" (LUKE-nuh)- derived from the Greek for "lamp".
I totally agree that we need some more ordinary sounding, shorter names for polytopes.
Names that sound like they could be actual English words. (Like "vabe", "cune", or "shollus")
We should put our heads together and come up with something everyone can agree on!
Keiji, your system is a great start. My only complaint is that it sounds very foreign.
What if we somehow anglicized it (even more)?
for example, "cote" (sounds like "coat") instead of koto. Or "Cotone"..
