We present results on the transition from semiclassical to classical behavior of a nonlinear chaotic quantum system as a function of coupling to the environment as well as system size. These results show several surprises about the behavior of the semiclassical Lyapunov exponents and the range of validity of the classical equations, and in particular how they depend upon the degree of chaos in the classical or semiclassical system.
