    "abstract": "We build, using group-theoretic methods, a general framework for approaching\nmulti-particle entanglement. As far as entanglement is concerned, two states of\nn spin-1/2 particles are equivalent if they are on the same orbit of the group\nof local rotations (U(2)^n). We give a method for finding the number of\nparameters needed to describe inequivalent n spin-1/2 particles states. We also\ndescribe how entanglement of states on a given orbit may be characterized by\nthe stability group of the action of the group of local rotations on any point\non the orbit.",
