What is a 99 sided shape called?

Polygons with 21 to 99 sides have a different system. Take the prefix for the tens digit (found on the left column), the ones digit (right column below), and then stick a “kai” between them to get (tens)kai(ones)gon . The 3-digit sided polygons are named in a similar fashion. A 100-sided polygon is called a hectogon.
