Description
The number of transpositions that are smaller or equal to a permutation in Bruhat order.
A statistic is known to be smooth if and only if this number coincides with the number of inversions. This is also equivalent for a permutation to avoid the two pattern $4231$ and $3412$.
Code
def statistic(pi):
    n = len(pi)
    B = Permutations(n).bruhat_poset(facade=True)
    return sum(Integer(1) for tau in B.principal_order_ideal(pi) if len(tau.fixed_points()) == n-2)
