>>10824569Number with only identity and itself as factor.
Sounds fine.
Problem is, that two creates periodic patterns in certain stuff. Prime numbers don't.
I think there is some relation to be like...
It is not prime when addition of identity (once) defines identity of which addition and multiplication with by itself is same.
Then it's not prime.
"" 2+2 = 4 "" 2*2 = 4 ""
It's maybe 0th prime number, ( just by itself, itself and identity )
It's specific identity for sure. I don't know if it's prime, but for sure 2 is much different in this aspect from other prime number.
