Description
The number of descents of a set partition. The Mahonian representation of a set partition {B1,,Bk} of {1,,n} is the restricted growth word w1wn} obtained by sorting the blocks of the set partition according to their maximal element, and setting wi to the index of the block containing i. The word w has a descent at position i if wi>wi+1.

Description
The number of occurrences of the contiguous pattern {{{[[.,.],[.,.]]}}} in a binary tree. Equivalently, this is the number of branches in the tree, i.e. the number of nodes with two children. Binary trees avoiding this pattern are counted by 2n2.

Description
The number of leaf nodes in a binary tree. Equivalently, the number of cherries [1] in the complete binary tree. The number of binary trees of size n, at least 1, with exactly one leaf node for is 2n1, see [2]. The number of binary tree of size n, at least 3, with exactly two leaf nodes is n(n+1)2n2, see [3].

Description
The jump number of the poset. A jump in a linear extension e1,,en of a poset P is a pair (ei,ei+1) so that ei+1 does not cover ei in P. The jump number of a poset is the minimal number of jumps in linear extensions of a poset.
