The LaTeX DLMF and DRMF macro \Racah represents the Racah polynomial.

This macro is in the category of polynomials.

In math mode, this macro can be called in the following ways:

\Racah{n} produces Failed to parse (unknown function "\Racah"): {\displaystyle {\displaystyle \Racah{n}}}
\Racah{n}@{x}{\alpha}{\beta}{\gamma}{\delta} produces Failed to parse (unknown function "\Racah"): {\displaystyle {\displaystyle \Racah{n}@{x}{\alpha}{\beta}{\gamma}{\delta}}}

These are defined by Failed to parse (unknown function "\Racah"): {\displaystyle {\displaystyle \Racah{n}@{\lambda(x)}{\alpha}{\beta}{\gamma}{\delta} {}:=\HyperpFq{4}{3}@@{-n,n+\alpha+\beta+1,-x,x+\gamma+\delta+1}{\alpha+1,\beta+\delta+1,\gamma+1}{1}, }}

where and or or with a nonnegative integer.
