Works for inputs 1, 3, 11, 13, 15, 17, 19.

Total length is 31*(1+3+11+13+15+17+19) = 2449.

Explanation:

    """""""""""..."""""""""""    Push five empty strings, a long string,
                                    and five more empty strings.
    ]]]]]]]]]]]sssssssssss       Collect them all in a list. Put that list in
                                 10 more layers of list, for good measure.
                                 Convert this to a string, to just get the long one.
    BBBBBBBBBBB///////////       Split into chunks of size
                                    11/(11/(.../(11/(11/11))))) = 11.
                                 This gets us:
                                    ["DDDDDDDDDDD" "ooooooooooo" ...]
    zzzzzzzzzzz                  Transpose eleven times, i.e. once. We now have:
                                    ["Do not..." "Do not..." ... "Do not..."]
    ___________&&&&&&&&&&&       Push eleven more copies, and get the unique elements.
                                 This gets us:
                                    ["Do not..."]
