    "abstract": "We investigate the entanglement properties of multi-mode Gaussian states,\nwhich have some symmetry with respect to the ordering of the modes. We show how\nthe symmetry constraints the entanglement between two modes of the system. In\nparticular, we determine the maximal entanglement of formation that can be\nachieved in symmetric graphs like chains, 2d and 3d lattices, mean field models\nand the platonic solids. The maximal entanglement is always attained for the\nground state of a particular quadratic Hamiltonian. The latter thus yields the\nmaximal entanglement among all quadratic Hamiltonians having the considered\nsymmetry.",
