# I've redirected enneagonal number to nonagonal number.

False.

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 accessible

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.

::An illustration made this crystal clear for me; the article should have one (I'll put it on the todo list). For now, you could take a look at [http://mathworld.wolfram.com/NonagonalNumber.html] If you count the dots in the third nonagon, there ought to be 24 of them. PrimeFan 22:23, 2 March 2007 (UTC)

::: Thank, that does make it clear (thought perhaps does not motivate why it is interesting or useful). So, does it have anything to do with figurate? --Jake 00:44, 8 March 2007 (UTC)
