A prime-representing quadratic-exponent conjecture following Mills

Let f(n)=A(n+1)2f(n)=\lfloor A^{(n+1)^2}\rfloor for a positive constant AA.

Prime-representing function conjecture. There is a constant AA, possibly near 1.19667465007057640221.1966746500705764022, such that f(n)f(n) is prime for every integer n1n\geq 1.

This conjecture proposes a deterministic prime-representing function with quadratic exponents, analogous to Mills' formula. The stated value of AA is experimental, and the conjecture remains open.
