    "abstract": "We show that not all 4-party pure states are GHZ reducible (i.e., can be\ngenerated reversibly from a combination of 2-, 3- and 4-party maximally\nentangled states by local quantum operations and classical communication\nasymptotically) through an example, we also present some properties of the\nrelative entropy of entanglement for those 3-party pure states that are GHZ\nreducible, and then we relate these properties to the additivity of the\nrelative entropy of entanglement.",
