My nomenclature was not meant to be exact, but I added "(non-trivial)" since the entire array and the empty array are trivial to me. Nor did I mention in what respect "minimal" and "maximal" was. I think with respect to the rank, or dimension if you prefer. All items have maximal rank (_1) and all atoms have minimal rank (0).
