A note on Krawtchouk polynomials and Riordan arrays. (English) Zbl 1152.33310
Summary: We study links between Krawtchouk polynomials and Riordan arrays of both the ordinary kind and the exponential kind. We derive summation formulas for values of the Krawtchouk polynomials using the A-sequences of the Riordan arrays.
