Jun 1, 2020 at 1:34 comment added David Galvin @RichardStanley I have corrected the sum --- the power of $\beta$ should have been $j$ rather than $n$.

Corrected typo in summation --- power of $\beta$ should have been $j$, not $n$.
Jun 1, 2020 at 0:30 comment added Richard Stanley The factor $\beta^n$ seems superfluous.
May 31, 2020 at 20:49 comment added David Galvin Yes, my sum has a falling rather than a rising power. But as observed in a comment in the earlier question, when the argument of the Pochhammer symbol is constant (not depending on n), there's not any difference in difficulty between falling and rising power.
May 31, 2020 at 20:39 comment added Carlo Beenakker your earlier question had a rising factorial (Pochhammer) instead of a falling factorial, is that intentional?
