Query: A relation for a class of Racah polynomials   In this paper we derive a relation for a class of Racah polynomials that
appear in a conjecture of Kresch and Tamvakis. The relation follows from an
inversion formula for a transformation of a discrete sequence of complex
numbers $\{ x_n \}_{n=0}^{\infty}$. As a result of our inversion formula, we
also obtain other combinatorial identities.
