*1 is the 0th Prime.
It stops at p (18), for 61+18+2 is 81
61+18-2 is 77
You hear that? It's the CIA knocking at your door. You better not answer but flee
For what?
With the odds, or at p(2n-1), +/-1 works for another finite span.
2+1-1 is 3
5+3-1 is 7
11+5+1
17+7-1 is 23
23+9-1 is 31
31+11+1+/-1
41+13-1
47+15-1 is 61
59+17+1 is composite, as is 59+17-1
If p(n) can be designated as the nth Prime.
Then
p(2n)+/-2 shall be Prime, when adding or subtracting 2!
1+1+0
