A terrace for Z_{m} is a particular type of sequence formed from the m elements of Z_{m}. For m\ud odd, many procedures are available for constructing power-sequence terraces for Z_{m}; each terrace of this\ud sort may be partitioned into segments, of which one contains merely the zero element of Z_{m}, whereas\ud every other segment is either a sequence of successive powers of an element of Z_{m} or such a sequence\ud multiplied throughout by a constant. We now refine this idea to show that, for m=n−1, where n is an odd prime power, there are many ways in which power-sequences in Z_{n} can be used to arrange the elements of Z_{n} \ {0} in a sequence of distinct entries i, 1 ≤ i ≤ m, usually in two or more segments, which becomes a terrace for Z_{m} when interpreted modulo m instead of modulo n. Our constructions provide terraces for Z_{n-1} for all prime powers n satisfying 0 < n < 300 except for n = 125, 127 and 257.
