Description
The minimal number with no two order isomorphic substrings of this length in a permutation.
For example, the length $3$ substrings of the permutation $12435$ are $124$, $243$ and $435$, whereas its length $2$ substrings are $12$, $24$, $43$ and $35$.
No two sequences among $124$, $243$ and $435$ are order isomorphic, but $12$ and $24$ are, so the statistic on $12435$ is $3$.
This is inspired by St000922The minimal number such that all substrings of this length are unique..
Code
def statistic(w):
    from sage.combinat.permutation import to_standard
    for k in range(1,len(w)+1):
        S = []
        for i in range(len(w)-k+1):
            s = to_standard(w[i:i+k])
            if s in S:
                break
            else:
                S.append(s)
        else:
            return k
