    "abstract": "A geometrical description of three qubit entanglement is given. A part of the\ntransformations corresponding to stochastic local operations and classical\ncommunication on the qubits is regarded as a gauge degree of freedom. Entangled\nstates can be represented by the points of the Klein quadric ${\\cal Q}$ a space\nknown from twistor theory. It is shown that three-qubit invariants are\nvanishing on special subspaces of ${\\cal Q}$. An invariant vanishing for the\n$GHZ$ class is proposed. A geometric interpretation of the canonical\ndecomposition and the inequality for distributed entanglement is also given.",
