Prime and Composite Numbers
I just re-did the Prime and Composite Numbers page.
Any comments or suggestions?

Re: Prime and Composite Numbers
I didnt find anything wrong with that page, but I followed a link to this page and noticed this.
Euclid proved that 2[sup]n−1[/sup](2[sup]n[/sup]−1) is an even perfect number when 2[sup]n[/sup]-1 is a Mersenne prime. These are now called Euclid numbers
Are you sure??
