Query: Exchange symmetry and global entanglement and full separability   Ichikawa et al. [Phys. Rev. A 78, 052105 (2008)] showed that exchange
symmetry gives rise to simple characterization of whether multipartite pure
quantum states being either globally entangled or fully separable. In this
Brief Report, we provide a simple alternative approach and some extension to
their conclusions.
