3 to 100 sided polygons names?

If you wish to communicate information, I suggest you a 67-sided figure a 67-gon. Although there are prefices I suggest you keep it simple. Not only is the use of long and unfamiliar Greek prefices pretentious, you will only annoy the reader who will probably have to consult a dictionary. Names are used mainly for 3-12 sides and for 20.

Having said that, if you do want to be pretentious or obfuscate, you can use the link below for polygons with up to 999 sides.
