nd by &quot;sum&quot; in a given setting.
    For example, if y is simply the set {y_1, y_2, y_3}, then y is something that can
    be said to exist &quot;over and above&quot; its elements, at least, in some sense, even in
    the case of a singleton set, say, z = {z_1}.  But any claim of &quot;emergence&quot; for
    the relationship of a set to its elements would most likely be discounted as
    trivial, since the set is defined as something that is fully determined by
    its elements.
