Best Answer

A polygon with more than twenty sides consists of a prefix, the connector -kai- to represent a number of sides in the tens, and the prefix for eight, before the suffix -gon, meaning "angle", or "knee". The prefix representing 20 is icosa- (or icosi- when dealing with polygons including a non-zero unit number), while the connector for 8 is -octa-, (from the Greek okta, meaning eight). Therefore, a twenty-eight sided regular polygon would be called an icosikaioctagon.

With that said, it is more logical, and much less ambiguous, to use the phrasing n-gon when referring to shapes of around 21 sides or more - for example, a twenty-eight sided figure would be referred to as a 28-gon. A one hundred sided figure, similarly, would be called a 100-gon.
