Talk:Polygonal number
From Wikipedia, the free encyclopedia
I think that the correct formula for Polygonal Numbers is p(a,s)=[(a-2)s-(a-4)]s/2 where 'a' represent the number of angles and 's' the length of the sides of a regular polygon.
In the Wikipedia's text it seems that there is a mistake in it. Check it!

- Looks like you're right — the formula as stated for s-polygonal numbers doesn't match up with the formulas given for specific cases. I've corrected it. Factitious 11:50, Nov 15, 2004 (UTC)

OK! It seems all-correct now! Raul Nunes (raulnunes@threebirds.com.br)
[edit] I have added some links to a video Podcast and they were remove
Hi everyone I have added some links to a video podcast that I own. I think they are a nice addition to wikipedia please look at them and express you oppinion here , judge for yourself if the links are really useful or not to wikipedia.
