There are , 5, different equivalence classes

        For the equivalence class of patterns, {{[3, 2, 1], [1, 2, 3]}}

         the member , {[3, 2, 1], [1, 2, 3]}, has a scheme of depth , 2

                                  here it is:

{[[], {}, {}], [[1], {[3, 0], [0, 3]}, {}],

    [[2, 1], {[1, 0, 0], [0, 2, 0], [0, 1, 2], [0, 0, 3]}, {1}],

    [[1, 2], {[0, 0, 1], [0, 2, 0], [2, 1, 0], [3, 0, 0]}, {1}]}

                 Using  the scheme, the first, , 31, terms are

[1, 1, 2, 4, 4, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,

    0, 0, 0, 0, 0]

                             the sequence is finite

For the equivalence class of patterns, {{[3, 2, 1], [1, 3, 2]},

{[[], {}, {}], [[1, 2], {[0, 1, 0]}, {1}], [[1], {}, {}],

    [[2, 1], {[1, 0, 0]}, {1}]}

                 Using  the scheme, the first, , 31, terms are
