Dual q-Hahn polynomials

The polynomials are given in terms of basic hypergeometric functions. ${\displaystyle R_{n}(q^{-x}+\gamma \delta q^{x+1},\gamma ,\delta ,N|q)={}_{3}\phi _{2}\left[{\begin{matrix}q^{-n},q^{-x},\gamma \delta q^{x+1}\\\gamma q,q^{-N}\end{matrix}};q,q\right],\quad n=0,1,2,...,N}$
