     to investigate non-linear dynamical systems, like for instance artificial satellites, solar system, exoplanets or galactic models, it is necessary to have at hand several tools, such as a reliable dynamical indicator.the aim of the present work is to test a relatively new fast indicator, the mean exponential growth factor of nearby orbits (megno), since it is becoming a widespread technique for the study of hamiltonian systems, particularly in the field of dynamical astronomy and astrodynamics, as well as molecular dynamics.

    in order to perform this test we make a detailed numerical and statistical study of a sample of orbits in a triaxial galactic system, whose dynamics was investigated by means of the computation of the finite time lyapunov characteristic numbers (ft-lcns) by other authors.
