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 "isometry and automorphisms of constant dimension codes"):
  Abstract: We define linear and semilinear isometry for general subspace codes, used for random network coding. Furthermore, some results on isometry classes and automorphism groups of known constant dimension code constructions are derived.

Includes members:
  Member "cyclic orbit codes":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "the lattice structure of linear subspace codes")
  Member "canonical forms and automorphisms in the projective space":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "message encoding and retrieval for spread and cyclic orbit codes")
  Member "an algebraic approach for decoding spread codes":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "geometric decoding of subspace codes with explicit schubert calculus applied to spread codes")
