human: Given a node-centered hypergraph: <hypergraph>, where nodes represent papers and hyperedges represent sets of papers co-cited by a source paper.

Details of the hypergraph:
Center node: "primitive digraphs with large exponents and slowly synchronizing automata"
  Abstract: We present several infinite series of synchronozing automata for which the minimum length of reset words is close to the square of the number of states. All these automata are tightly related to primitive digraphs with large exponents. Bibliography: 28 titles.
