Consider the equation $$(x+1)(xy+1)=z^3,$$ where $x,y$ and $z$ are positive integers with $x$ and $y$ both at least $2$ (and so $z$ is necessarily at least $3$). For every $z\geq 3$, there exists the solution $$x=z-1 \quad \text{and} \quad y=z+1.$$ My question is, if one imposes the constraint that $$x^{1/2} \leq y \leq x^2 \leq y^4,$$ can there be any other integer solutions (with $x,y \geq 2$)? Moreover, $z$ may be assumed for my purposes to be even with at least three prime divisors. Thank you in advance for any advice. Edit: there was a typo in my bounds relating $x$ and $y$.
