We consider the possible complexity of the set of reals belonging to an inner model M of set theory. We show that if this set is analytic then either l-2, M is countable or else all reals are in M. We also show that if an inner model contains a superperfect set of reals as a subset then it contains

A simple formalism of real irreducible tensorial sets of real bases is proposed. The definition of the real bases, the coupling of the real bases, and the transformation of the real bases in a group chain including the three-dimensional rotation group and the molecular point groups are studied. The
