The multi-qubit GHZ state possesses tangles with elegant transformationproperties under stochastic local operations and classical communication. Sincealmost all pure 3-qubit states are connected to the GHZ state via SLOCC, wederive a necessary and sufficient achievability inequality on arbitrary 3-qubittangles, which is a strictly stronger constraint than both the monogamyinequality and the marginal eigenvalue inequality. We then show thatentanglement shared with any single party in the n-qubit GHZ SLOCC equivalenceclass is precisely accounted for by the sum of its k-tangles, recently coinedthe strong monogamy equality, acknowledging competing but agreeing definitionsof the k-tangle on this class, one of which is then computable for arbitrarymixed states. Strong monogamy is known to not hold arbitrarily, and so weintroduce a unifying outlook on entanglement constraints in light of basic realalgebraic geometry.
