摘要：

Entanglement types of pure states of three spin-1/2 particles are classified by means of their stabilizers in the group of loci unitary transformations. It is shown that the stabilizer is generically discrete, and that a larger stabilizer indicates a stationary value for some local invariant. We describe all the exceptional states with enlarged stabilizers.
