Description
The number of minimal elements in Bruhat order not less than the permutation. The minimal elements in question are biGrassmannian, that is 1r  a+1b  r+1a  b+1 for some (r,a,b). This is also the size of Fulton's essential set of the reverse permutation, according to [ex.4.7, 2].

Description
The number of blocks in the set partition. The generating function of this statistic yields the famous [[wiki:Stirling numbers of the second kind|Stirling numbers of the second kind]] S2(n,k) given by the number of [[SetPartitions|set partitions]] of {1,,n} into k blocks, see [1].

Description
The number of topologically connected components of a set partition. For example, the set partition {{1,5},{2,3},{4,6}} has the two connected components {1,4,5,6} and {2,3}. The number of set partitions with only one block is [[oeis:A099947]].

Description
The number of weak exceedances (also weak excedences) of a permutation. This is defined as wex(σ)=#{i:σ(i)i}. The number of weak exceedances is given by the number of exceedances (see [[St000155]]) plus the number of fixed points (see [[St000022]]) of σ.

Description
The number of exceedances (also excedences) of a permutation. This is defined as exc(σ)=#{i:σ(i)>i}. It is known that the number of exceedances is equidistributed with the number of descents, and that the bistatistic (exc,den) is [[Permutations/Descents-Major#Euler-Mahonian_statistics|Euler-Mahonian]]. Here, den is the Denert index of a permutation, see [[St000156]].
The following 4 statistics, ordered by result quality, also match your data. Click on any of them to see the details.
St000083The number of left oriented leafs of a binary tree except the first one. St000354The number of recoils of a permutation. St001863The number of weak excedances of a signed permutation. St001626The number of maximal proper sublattices of a lattice.
