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: "construction of n n 4 3 q quantum codes for odd prime power q"
  Abstract: For each odd prime power q, let 4{<=}n{<=}q{sup 2}+1. Hermitian self-orthogonal [n,2,n-1] codes over F{sub q}{sup 2} with dual distance three are constructed by using finite field theory. Hence, [[n,n-4,3]]{sub q} quantum maximal-distance-separable (MDS) codes for 4{<=}n{<=}q{sup 2}+1 are obtained.
