Abstract
Representation theory is shown to be incomplete in terms of enumeratin g all integrable limits of quantum systems. As a consequence, one can find exactly solvable Hamiltonians which have apparently strongly brok en symmetry. The number of these hidden symmetries depends upon the re alization of the Hamiltonian.
