Query: Large-scale numerical investigations of the antiferromagnetic Heisenberg
  icosidodecahedron   We present up to date investigations of the antiferromagnetic Heisenberg
icosidodecahedron by means of the Density Matrix Renormalization Group method.
We compare our results with modern Correlator Product State as well as Lanczos
calculations.
