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 "flat zipper unfolding pairs for platonic solids"):
  Abstract: We show that four of the five Platonic solids' surfaces may be cut open with a Hamiltonian path along edges and unfolded to a polygonal net each of which can "zipper-refold" to a flat doubly covered parallelogram, forming a rather compact representation of the surface. Thus these regular polyhedra have particular flat "zipper pairs." No such zipper pair exists for a dodecahedron, whose Hamiltonian unfoldings are "zip-rigid." This report is primarily an inventory of the possibilities, and raises more questions than it answers.

Includes members:
  Member "enumerating foldings and unfoldings between polygons and polytopes":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "which convex polyhedra can be made by gluing regular hexagons")
  Member "examples counterexamples and enumeration results for foldings and unfoldings between polygons and polytopes":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "ununfoldable polyhedra with convex faces")
