Recurrence Relations for Some Integer Sequences Related to Ward Numbers

Abstract: In this paper, we give recurrence relations and identities for some integer sequences related to Ward numbers such as Ward-Lah numbers, varied Ward numbers and binomial Ward numbers. Most of the sequences are entered in the On-Line Encyclopedia of Integer Sequences. We give triangular recurrence relations, horizontal recurrence relations, exponential generating functions and some recurrence relations of higher order obtained by using Sister Celine's general algorithm.
