Abstract
We propose a scheme for classifying the entanglement of a tripartite pure qubit state. This classification scheme consists of an ordered list of seven elements. These elements are the Cayley hyper-determinant, and its six associated subdeterminants. In particular we show that this classification provides a necessary and sufficient condition for separability.
