    "abstract": "Representation theory is shown to be incomplete in terms of enumerating all\nintegrable limits of quantum systems. As a consequence, one can find exactly\nsolvable Hamiltonians which have apparently strongly broken symmetry. The\nnumber of these hidden symmetries depends upon the realization of the\nHamiltonian.",
