Description
The number of external nodes of a binary tree.
That is, the number of nodes that can be reached from the root by only left steps or only right steps, plus 1 for the root node itself. A counting formula for the number of external node in all binary trees of size n can be found in [1].

Description
The number of indices that are either left-to-right maxima or right-to-left minima.
The (bivariate) generating function for this statistic is (essentially) given in [1], the mid points of a 321 pattern in the permutation are those elements which are neither left-to-right maxima nor a right-to-left minima, see [[St000371]] and [[St000372]].

Description
The number of saliances of the permutation.
A saliance is a right-to-left maximum. This can be described as an occurrence of the mesh pattern ([1],(1,1)), i.e., the upper right quadrant is shaded, see [1].

Description
The number of left-to-right-maxima of a permutation.
An integer σi in the one-line notation of a permutation σ is a '''left-to-right-maximum''' if there does not exist a j<i such that σj>σi.
This is also the number of weak exceedences of a permutation that are not mid-points of a decreasing subsequence of length 3, see [1] for more on the later description.

Description
The number of indices greater than or equal to 2 of a permutation such that all smaller indices appear to its right.
For a permutation π of length n, this is the number of indices 2≤j≤n such that for all 1≤i<j, the pair (i,j) is an inversion of π.
