Description
Number of minimal entries in the Bruhat order matrix of a permutation.
Associate to a permutation $\sigma$ of length $n$ the $n \times n$ matrix with entries
$$r_{ij}(\sigma) = \left| \big\{ u \in \{1,\dots,i\} \mid \sigma(u) \leq j \big\}\right|.$$
For the identity permutation, one has $r_{ij} = \min\{i,j\}$, and $\sigma \leq \tau$ in the (strong) Bruhat order if and only if $r_{ij}(\tau) \leq r_{ij}(\sigma)$ for all $i,j$.
This statistic records the number of indices $i,j$ with $r_{ij} = \min\{i,j\}$.
Code
def B(sigma):        
    n = len(sigma)                                                                 
    return Matrix([[sum(1 for u in [1 .. i] if sigma(u) <= j) for i in [1 .. n]] for j in [1 .. n]])

def statistic(sigma):
    n = len(sigma)
    M = B(sigma)
    return sum(1 for i in range(n) for j in range(n) if M[i,j] == min(i,j))
