${\displaystyle{\displaystyle{\displaystyle q^{-n}(1-q^{n})(1-abcdq^{n-1}){\mathcal{P}}_{n}(z){}=A(z){\mathcal{P}}_{n}(qz)-\left[A(z)+A(z^{-1})\right]{\mathcal{P}}_{n}(z)+A(z^{-1}){\mathcal{P}}_{n}(q^{-1}z)}}}$

Substitution(s)

${\displaystyle{\displaystyle{\displaystyle A(z)=\frac{(1-az)(1-bz)(1-cz)(1-dz)}{(1-z^{2})(1-qz^{2})}}}}$ &
${\displaystyle{\displaystyle{\displaystyle{\mathcal{P}}_{n}(z):=\frac{\left(ab,ac,ad;q\right)_{n}}{a^{n}}\,\qHyperrphis{4}{3}@@{q^{-n},abcdq^{n-1},az,az^{-1}}{ab,ac,ad}{q}{q}}}}$
