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)
