Statistic identifier: St000847

-----------------------------------------------------------------------------
Collection: Binary words

-----------------------------------------------------------------------------
Description: The number of standard Young tableaux whose descent set is the binary word.

A descent in a standard Young tableau is an entry $i$ such that $i+1$ appears in a lower row in English notation.

For example, the tableaux $[[1,2,4],[3]]$ and $[[1,2],[3,4]]$ are those with descent set $\{2\}$, corresponding to the binary word $010$.

Code:
def statistic(w):
    D = [i+1 for i in range(len(w)) if w[i]==1]
    return len([T for T in StandardTableaux(len(w)+1)
                if T.standard_descents() == D])
