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 "some new results on the self dual 120 60 24 code"):
  Abstract: The existence of an extremal self-dual binary linear code of length 120 is a long-standing open problem. We continue the investigation of its automorphism group, proving that automorphisms of order 8, 30 and 57 cannot occur. Supposing the involutions acting fixed point freely, we show that the automorphism group is of order at most 120, with further restrictions. Finally, we present some necessary conditions for the existence of the code, based on its shadow and on design theory.
