Query: Ramanujan-Bernoulli numbers as moments of Racah polynomials   The classical sequence of Bernoulli numbers is known to the the sequence of
moments of a family of orthogonal polynomials. Some similar statements are
obtained for another sequence of rational numbers, which is similar in many
ways to the Bernoulli numbers.
