    "abstract": "We compare the polynomial invariants for four qubits introduced by Luque and\nThibon, PRA {\\bf 67}, 042303 (2003), with optimized Bell inequalities and a\ncombination of two qubit concurrences. It is shown for various parameter\ndependent states from different SLOCC classes that it is possible to measure a\ngenuine 4-qubit entanglement with these polynomials.",
