>>10936503I found it in a vision:
A^n - B^n - 1 divided by n where A+B = n and A-B = n
if n can divide A^n - B^n - 1 evenly then n is a prime or pseudo prime as long as A+B = n and A-B = n
That means that for 5 it is
3^5 - 2^5 - 1 / 5 which divides evenly
but for 9
5^9 - 4^9 - 1 / 9 does not divide evenly
Apparently it works all the way up until 341 or something like that.
I found it from my french elestial girlfriend.
