What do you call a 199 sided shape?

Answer 1

For large numbers, mathematicians usually write the numeral itself, e.g.17-gon. A variable can even be used, usually n-gon. This is useful if the number of sides is used in a formula.

There is no established name for a 100-gon, though hectamay be used.

It can be called a hectakaienneacontakiaenneagon using the appropriate prefixes.

The -kai- portions above are optional meaning and.
