human: Given a hyperedge-centered hypergraph: <hypergraph>, where the center hyperedge is induced by one source paper and its member nodes are the cited papers.

Details of the hypergraph:
Center hyperedge (induced by source paper "some polycubes have no edge unzipping"):
  Abstract: It is unknown whether or not every polycube has an edge-unfolding. A polycube is an object constructed by gluing cubes face-to-face. An edge-unfolding cuts edges on the surface and unfolds it to a net, a non-overlapping polygon in the plane. Here we explore the more restricted edge-unzippings where the cut edges form a path. We construct two different polycubes neither of which has an edge-unzipping.

Includes members:
  Member "unfolding polyhedra":
    also connected through other hyperedges:
      (none)
  Member "unfolding orthogrids with constant refinement":
    also connected through other hyperedges:
      (none)
  Member "flat zipper unfolding pairs for platonic solids":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "common edge unzippings for tetrahedra")
