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: "minimal dfa for testing divisibility"
  Abstract: We present and prove a theorem answering the question "how many states does a minimal deterministic finite automaton (DFA) recognizing the set of base-b numbers divisible by k have?"

Connected through hyperedge HE-1 (induced by source paper "minimal automaton for multiplying and translating the thue morse set"):
  with members:
    - "state complexity of the multiples of the thue morse set"
    - "ultimate periodicity of b recognisable sets a quasilinear procedure"
    - "enumeration and decidable properties of automatic sequences"
    - "the growth function of s recognizable sets"
    - "periodicity repetitions and orbits of an automatic sequence"

Connected through hyperedge HE-2 (induced by source paper "state complexity of the multiples of the thue morse set"):

    - "periodicity repetitions and orbits of an automatic sequence"
    - "real numbers having ultimately periodic representations in abstract numeration systems"
    - "numeration systems on a regular language"
