Except 2, every prime is odd.
A prime larger than 10 must end with {1,3,7,9}
Prime occurs irregularily.
There are infinite number of primes. (If there's a finite set of primes, we can have a product of the elements in the set + 1 which is not divisible by any of the elements).
So, how would I generalize occurance of primes if it's irregular?
Neglecting the first row, each row can have max of 4 primes.
02nd row has 4 primes (-1 -3 -7 -9).
03rd row has 2 primes ( -3 -9).
04th row has 2 primes (-1 -7 ).
05th row has 3 primes (-1 -3 -7 ).
06th row has 2 primes ( -3 -9).
07th row has 2 primes (-1 -7 ).
08th row has 3 primes (-1 -3 -9).
09th row has 2 primes ( -3 -9).
10th row has 1 prime! ( -7 ).
