The integers $ a_n=\sum_{k=0}^n{\binom nk}^2{\binom{n+k}k}^2, n=0,1,2,... $ appear as denominators of rational approximations to $\zeta(3)=\sum_{k=1}^\infty k^{-3}$ in Apery's proof of the irrationality of $\zeta(3)$. The sequence satisfies a polynomial recursion, namely, $ (n+1)^3a_{n+1}-(2n+1)(17n^2+17n+5)a_n+n^3a_{n-1}=0$, where $n=0,1,2,...$, and admits several curious congruence properties. ...
