This paper shows some of fundamental properties of Z4sequences of combining each element of a preferred pair of binary m-sequences by using the Gray code mapping. The distribution of elements {0,1,2,3} within one period can be exactly derived from auto/cross-correlation values of Gold sequences or Gold-like sequences. In addition, this paper shows properties such that the Z4 sequences have near-optimum correlation properties.
