From the analysis of results obtained for systems of linear sizes $3\le L\le 8$ we conclude that the stiffness exponent of the model is positive. This implies the existence of a stable ordered phase at low but finite temperatures.4 pages Latex. 3 postscript figures. Submitted to Phys. Rev. BDisordered Systems and Neural Networkstext
