This generalizes to arbitrary subset systems the result of Markowsky (T.C.S. 4 (1977), pp. 125–135) for chains, and the completions of Wright, Wagner, and Thatcher for union complete Z; our method, different from theirs, uses the time-honored direct construction of universal maps. Further, we obtain some results on the internal structure of
