Abstract: On page 1 of his book Algebraic Numbers and Diophantine Approximation, K. B. Stolarsky posed the problem of solving the equation ${y^2} + 999 = {x^3}$ in positive integers. In the present paper we refine some techniques of Ellison and Pethö and show that the complete set of integer solutions of Stolarsky's equation is

$\begin{displaymath}\begin{array}{*{20}{c}} {x = 10,} \hfill & {y = \pm 1,} \hfil... ...l \\ {x = 174,} \hfill & {y = \pm 2295,} \hfill \\ \end{array} \end{displaymath}$

and

$\displaystyle x = 22480,\quad y = \pm 3370501.$
