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: "a note on linear codes and nonassociative algebras obtained from skew polynomial rings"
  Abstract: Different approaches to construct linear codes using skew polynomials can be unified by using the nonassociative algebras built from skew-polynomial rings by Petit.

Connected through hyperedge HE-1 (induced by source paper "how to obtain lattices from f sigma delta codes via a generalization of construction a"):
  with members:
    - "on skew polynomial codes and lattices from quotients of cyclic division algebras"
    - "information bit error rate and false positives in an mds code"
    - "finite nonassociative algebras obtained from twisted polynomials over chain rings"
    - "the nonassociative algebras used to build fast decodable space time block codes"
    - "on self dual mrd codes"
    - "a circulant approach to skew constacyclic codes"
    - "quotients of orders in cyclic algebras and space time codes"
    - "iterated space time code constructions from cyclic algebras"

Connected through hyperedge HE-2 (induced by source paper "finite nonassociative algebras obtained from twisted polynomials over chain rings"):
  with members:
    - "how to obtain lattices from f sigma delta codes via a generalization of construction a"
    - "on skew polynomial codes and lattices from quotients of cyclic division algebras"
    - "the nonassociative algebras used to build fast decodable space time block codes"
