Abstract

Associated Stirling numbers of first and second kind are usually found in the literature in various forms of stairs depending on their order r. Yet, it is shown in this note that all of these numbers can be arranged, through a linear transformation, in the same arithmetical triangle structure as the “Pascal’s triangle”.
