Naming Polygons with multiple 100's of sides

As mentioned in the table at polygon, the name for a 10-sided figure is decagon, but the names of polygons from 30 to 90 sides are n-contagons, not n-decagons. For example, a 30-sided figure is a tricontagon.

Similary, the correct names for polygons from 300 to 900 sides would be n-cosagons even though a 100-sided figure is a hectagon.

For the 1000's, it is "chilia" in both cases; that is, a 1000-sided figure is a chiliagon and polygons from 3000 to 9000 are n-chiliagons (that is, a 3000-sided figure is a trichiliagon.) Same with the 10,000's, where it is "myria", the only difference is that it doesn't stop at 10. A 100,000-sided figure is a decamyriagon, a million-sided figure is a hectamyriagon, and a 10-million-sided figure is a chiliamyriagon. Any corrections to this?? 66.245.82.186 15:02, 3 Aug 2004 (UTC)

A few: it's triaconta-, not triconta-, and -cosi- instead of -cosa- (although it's -cosakismyria- for some reason). Also, you're missing -kis- "times" for the larger numbers: it's chilia-, dischilia-, trischilia-, tetrakischilia-, ..., enneakischilia-, myria-, stepping in thousands from 1000 to 10000. The first eight powers of 10 are deca-, hecato- (or hecto-), chilia-, myria-, decakismyria-, hecatontakismyria-, chiliakismyria-, myriakismyria-.

User:Double sharp/Naming polygons has one of many possible consistent and etymologically motivated systems (this is the one I tend to use). I realize I'm transliterating kappa inconsistently as both k and c, but this was done out of a desire to keep the commonly known names. Double sharp (talk) 20:20, 14 March 2015 (UTC)
