You can plot the result in polar coordinates, or in linear coordinates. Either way the pattern is easily visible. And within it is the subset containing all prime numbers. There does not appear to be any simple way to reduce it to a single formula for the nth prime number.

Another variation — Ex-News Junkie, Tue Aug 8 7:31pmAll prime numbers P are a subset of SP = {2,3,5, and R + n x 30} where R = {1,7,11,13,17,19,23,29} n = {0,1,2,3,... } P is prime if (P mod SP) 0 It's simpler I suppose, but it loses the perspective... more

In fact it's even worse — Ex-News Junkie, Mon Sep 18 5:44pmIt is basically a plot of all odd numbers. The only reason they are prime numbers is because they've been checked beforehand to eliminate odd numbers that are multiples of smaller numbers. Every... more
