Using tensor product constructions for the first-order generalized Reed-culler codes, we extend the well-established concept of the Gray isometry between (Z(4), delta(L)) and (Z(2)(2), delta(H)) to the context of finite chain rings. Our approach covers previous results by Carlet, Constantinescu, Nechaev et al, and overlaps with Heise et al. and Hanold ct ar. Applying the Gray isometry on Z(9) we Obtain a previously unknown nonlinear ternary (36, 3(12), 15) code.
