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.
