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 minimal elements in Bruhat order not less than the permutation.
The minimal elements in question are biGrassmannian, that is
1…r a+1…b r+1…a 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 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.
The following 6 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. St000155The number of exceedances (also excedences) of a permutation. St000354The number of recoils of a permutation. St001237The number of simple modules with injective dimension at most one or dominant dimension at least one. St001508The degree of the standard monomial associated to a Dyck path relative to the diagonal boundary. St001863The number of weak excedances of a signed permutation.
