Another variation
Tue Aug 8, 2017 7:31pm

All prime numbers P are a subset of

SP = {2,3,5, and R + n x 30}

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 that I originally derived this as a geometric pattern when treating primes as angles on an Archimedes Spiral, or on a unit circle.

    Not sure about the notation, but here goes: The set of all prime numbers P is a subset of SP: SP = {2,3,5, and R + n x 360}, for n = {0,1,2,3,... } where R = { 1,7,11,13,17,19,23,29,... more

        If you write the numbers out from 1 to 30, then cross out all the even numbers, then cross out any number that is divisible by 3,5,7 or 9, what remains are the root angles. You can plot the result in ... more

          It 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
