Q-Racah polynomials
In mathematics, the q-Racah polynomials  are a family of basic hypergeometric orthogonal polynomials in the basic Askey scheme, introduced by . give a detailed list of their properties. Definition

The  polynomials are given in terms of basic hypergeometric functions and the Pochhammer symbol by 

They are sometimes given with changes of variables as
