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
