There is an "official" set of names for polygons, uniformly derived
from the Greek after 4 sides, and you have some of them wrong.

"septa" is Latin, not Greek - the official version is "hepta"

The typical twenty-something is (eg) "icositetra"

and the typical thirty-something is (eg) "tricontapenta"

(which would also tell you what the typical forty-something would be. JHConway
