Abstract
We show that three-party entanglement signals in holography obey a relation that is not satisfied by generalized Greenberger-Horne-Zeilinger (GHZ) states. This is the first known constraint on the structure of pure three-party holographic states, and shows that time-symmetric holographic states can never have a purely GHZ structure. We also discuss similar relations for four parties.
