... following example. Example (Regenerative hook partition structures. ) A partition λ of n is called a hook if it has at most one part larger than 1. The only regenerative partition structures p such that ... some partition λ and some part x ∈ λ implies that a partition structure regenerative according to d is trivial, (i.e. is either the pure-singleton partition with p(1 n...

... denote set partitions. The notation π  S means π is a set partition of the set S. The length (number of blocks) of π is denoted by (π). A set partition σ is called a refinement of a set partition ... corresponds a set partition s(G) such that two vertices v, w ∈ V are in the same block of s(G) if and only if there is a path in G from v to w. Equivalently, s(G) is the maximal set par...
