    "abstract": "We consider 3-parametric polynomials which replace the A-series interpolation\nMacdonald polynomials in the BC case. For these polynomials, we prove: an\nintegral representation, a combinatorial formula, Pieri-type rules, Cauchy\nidentity, and we also show that they do not satisfy any rational q-difference\nequation. We also prove a binomial formula for the 6-parametric Koornwinder\npolynomials.",
