"Icosikaihenagon" is a proper denomination for a 21-sided polygon, according to Wikipedia (see Polygon).

However, I doubt that even a well-read mathematician would understand precisely what this word is referring to (apart perhaps if the said mathematician is Greek).

"21-gon" would be a much more intelligible designation.
