Abstract
A symmetry of the parameter space of interacting boson models IBM-I and IBM -2 is studied. The symmetry is associated with linear canonical transformat ions of boson operators, or, equivalently, with the existence of different realizations of the symmetry algebras of the models, The relevance of the p arameter symmetry to physical observables is discussed.
