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: "two weight codes and second order recurrences"
  Abstract: Cyclic codes of dimension $2$ over a finite field are shown to have at most two nonzero weights. This extends a construction of Rao et al (2010) and disproves a conjecture of Schmidt-White (2002). We compute their weight distribution, and give a condition on the roots of their check polynomials for them to be MDS.

Connected through hyperedge HE-1 (induced by source paper "two weight codes over the integers modulo a prime power"):
  with members:
    - "determining the full weight distribution of any irreducible cyclic code over any finite field of dimension two"

Connected through hyperedge HE-2 (induced by source paper "how many weights can a cyclic code have"):
  with members:
    - "how many weights can a linear code have"
    - "maximum weight spectrum codes with reduced length"
    - "a note on full weight spectrum codes"
    - "maximum weight spectrum codes"
    - "the weights in mds codes"
    - "hamming weights in irreducible cyclic codes"
    - "weight distributions of hamming codes ii"
