Abstract
Based on the Lieb-Schultz-Mattis construction we present a five parameter family of Spin-1 Hamiltonians with degenerate groundstate. Starting from the critical symmetric Hamiltonian, we look for those perturbations of the symmetry, which leave the groundstate degenerate. We also discuss the spin-3/2 -case.
