    "abstract": "We construct GHZ contradictions for three or more parties sharing an\nentangled state, the dimension d of each subsystem being an even integer\ngreater than 2. The simplest example that goes beyond the standard GHZ paradox\n(three qubits) involves five ququats (d=4). We then examine the criteria a GHZ\nparadox must satisfy in order to be genuinely M-partite and d-dimensional.",
