Let Z/(pe) be the integer residue ring modulo pe with p an odd prime and e ≥ 2. We consider the suniform property of compressing sequences derived from primitive sequences over Z/(pe). We give necessary and sufficient conditions for two compressing sequences to be s-uniform with α provided that the compressing map is of the form ϕ(x0, x1,...,xe−1) = g(xe−1) + η(x0, x1,..., xe−2), where g(xe−1) is a permutation polynomial over Z/(p) and η is an (e − 1)-variable polynomial over Z/(p).
