Torsion subgroups in the units of the integral group ring of PSL(2,p^3)
  We show that for every prime $r$ all $r$-subgroups in the normalized units of the integral group ring of $\operatorname{PSL}(2,p^3)$ are isomorphic to subgroups of $\operatorname{PSL}(2,p^3)$. This answers a question of M. Hertweck, C.R. H\"ofert and W. Kimmerle for this series of groups.
