Query: Binomial identities related to Calabi-Yau differential equations   When searching for Calabi.Yau differential equations, often different
formulas for the coefficients give the same differential equation. The
coefficients are usually sums (simple, double or triple) of products of
binomial coefficients. This results in numerous binomial identities.
