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: "weight distribution of a p ary cyclic code"
  Abstract: For an odd prime $p$ and two positive integers $n\geq 3$ and $k$ with $\frac{n}{{\rm gcd}(n,k)}$ being odd, the paper determines the weight distribution of a $p$-ary cyclic code $\mathcal{C}$ over $\mathbb{F}_{p}$ with nonzeros $\alpha^{-1}$, $\alpha^{-(p^k+1)}$ and $\alpha^{-(p^{3k}+1)}$, where $\alpha$ is a primitive element of $\mathbb{F}_{p^n}$
