Mills' theorem states that there exists a positive real number $A$ such that the floor of the double exponential function $A^{3^n}$ are primes for all positive integers $n$. The value of $A$ is approximately $1.306$...., and primes generated by this constant A is $2,11,1361,....$, these are called as Mills' primes.
Now I want make some kind of generalization of this Mill's theorem: There exist 2 positive real numbers $B$ and $C$, such that the floor of the double exponential function $B^{C^n}$ are primes for all positive integers $n$. The values of $B$ and $C$ are chosen to be as smallest as possible, so it can generates the sequence of distinct increasing primes that are smallest as possible. I made an experiment and I have a problem of determining the values of $B$ and $C$, because it grows very fast. Does anyone able to determine the value of $B$ and $C$? What is the values of $B$ and $C$ might be?
