FORMULA
|
a(n) = A[n,n+2] = n-th prime p such that 2^2^(n+2) + p^2^(n+2) is prime.
|
|
|
EXAMPLE
|
a(1) = 13 because 13 is the first prime p such that 2^2^3 + p^2^3 is prime.
a(2) = 107 because 107 is the 2nd prime p such that 2^2^4 + p^2^4 is prime.
a(3) = 101 because 101 is the 3rd prime p such that 2^2^5 + p^2^5 is prime.
