    "abstract": "We discuss the symmetry of the parameter space of the interacting boson model\n(IBM). It is shown that for any set of the IBM Hamiltonian parameters (with the\nonly exception of the U(5) dynamical symmetry limit) one can always find\nanother set that generates the equivalent spectrum. We discuss the origin of\nthe symmetry and its relevance for physical applications.",
