We study properties of constant coefficient Laurent biorthogonal polynomialsusing Riordan arrays. We give details of related orthogonal polynomials, and weexplore relationships between the moments of these orthogonal polynomials, themoments of the defining Laurent biorthogonal polynomials, and the expansions of$T$-fractions. Closed form expressions are given for the polynomials and theirmoments.
