Let \(m\) and \(n\) be positive integers satisfying \(n^5 + 3n + 4 = 2^m\). Let the sum of all possible values of \(n\) be \(A\).

Let the sum of all positive integers \(x\) for which \(\lfloor A/4 \rfloor ( \lfloor A/2 \rfloor n + A - 1) (An + 2A - 1) + 9 \) is a perfect cube of a positive integer is \(B\).
