|To-do list for Nonagonal number:|
- How many people refer to a nine-sided polygon as an enneagon?
- Google results in 3,320 hits, while Google results in 1,770 hits. 
- Renaming the page would be in conflict with Wikipedia:Manual of Style#Usage and spelling.
- A redirect would be more appropriate.
- I've redirected enneagonal number to nonagonal number.

- MathWorld has "enneagonal" as an alias, not as the primary term.
Well, I think Eequor has pretty much covered all the bases, so I would just have to reiterate four of the things she has said in order to reach 5 sentences. PrimeFan 20:28, 19 Aug 2004 (UTC)
Not very accessibleEdit
I'm not understanding this page. I don't know what it means to represent a nonagon:
- A nonagonal number or enneagonal number is a figurate number that represents a nonagon.
Looking at figurate (which suggests that this is in 8 dimensions), nonagon (which suggests this is in 2 dimensions), and triangular number didn't provide much illumination. I think it would be useful to show how you get 24. Cheers, --Jake 18:37, 2 March 2007 (UTC)
