We constructively prove that the partially ordered set of finite permutations ordered by deletion of entries contains an infinite antichain.
A sefl-dual poset on objects counted by the Catalan numbers
Miklos Bona
We examine the poset of 132-avoiding -permutations ordered by descents. We show that this poset is the "coarsening" of the well-studied poset of noncrossing partitions .…
Enumeration of m-ary cacti
Miklos Bona, Michel Bousquet, Gilbert Labelle +1
The purpose of this paper is to enumerate various classes of cyclically colored m-gonal plane cacti, called m-ary cacti. This combinatorial problem is motivated by the topological…
