Abstract
For pure symmetric three-qubit states there are only three algebraically independent entanglement measures; one choice is the pairwise concurrence , the three-tangle , and the Kempe invariant . Using a canonical form for symmetric -qubit states derived from their Majorana representation, we derive the explicit achievable region of triples .
