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: "explicit msr codes with optimal access optimal sub packetization and small field size for d k 1 k 2 k 3"
  Abstract: This paper presents the construction of an explicit, optimal-access, high-rate MSR code for any $(n,k,d=k+1,k+2,k+3)$ parameters over the finite field $\fQ$ having sub-packetization $\alpha = q^{\lceil\frac{n}{q}\rceil}$, where $q=d-k+1$ and $Q = O(n)$. The sub-packetization of the current construction meets the lower bound proven in a recent work by Balaji et al. in \cite{BalKum}. To our understanding the codes presented in this paper are the first explicit constructions of MSR codes with $d<(n-1)$ having optimal sub-packetization, optimal access and small field size.
