Query: How to determine approximate Mixmaster parameters from numerical
  evolution of Einstein's equations   To assess the validity of the Belinskii, Khalatnikov, and Lifshitz (BKL)
approximation to Mixmaster dynamics, it would be useful to evaluate the BKL
discrete parameters as a byproduct of the numerical solution of Einstein's
equations. An algorithm to do this and results for a typical trajectory are
presented.
