Query: Defining the symmetry of the universal semi-regular autonomous
  asynchronous systems   The regular autonomous asynchronous systems are the non-deterministic Boolean
dynamical systems and universality means the greatest in the sense of the
inclusion. The paper gives four definitions of symmetry of these systems in a
slightly more general framework, called semi-regularity and also many examples.
