Abstract
The maximum Lyapunov exponent (referred to the mean
half-period of phase libration) of the motion in the chaotic layer
of a nonlinear resonance subject to symmetric periodic
perturbation, in the limit of infinitely high frequency of the
perturbation, has been numerically estimated by two independent
methods. The newly derived value of this constant is 0.80, with
precision presumably better than 0.01.
