We show that the three-qubit entanglement classes, (0) null, (1) separable A-B-C, (2a) biseparable A-BC, (2b) biseparable B-CA, (2c) biseparable C-AB, (3) W, and (4) Greenberger-Horne-Zeilinger, correspond respectively to ranks 0, 1, 2a, 2b, 2c, 3, and 4 of a Freudenthal triple system defined over the Jordan algebra C □C □ C. We also compute the corresponding stochastic local operations and classical communication orbits.
