Bergman clusters in two positions within the RD. The upper shell structure is produced on the body diagonal position, whereas the lower one is produced on the edge shared by the PR and the OR. The positional disorder on the soccerball shell and vacancies at the icosahedral shell are consistent with features observed in the PACs. Two Yb atoms located on the soccerball polyhedron form a short distance with Yb atoms at the RTH shell known to occur within the interstitial part (PR units) of the Takakura et al. (2007BB58) model.
