Correction to: 'Rigidity for groups with radical, cohomology of finite groups, and arithmeticity problems' by V.P.Platonov, Russian Math. Surveys 54 (1999), no. 1, 171-179

We apolologize for a mistake in translation in the article by V.P.Platonov in vol.54, no.1. The mistake occurs on p.172 line 27, p.173 line 23 and p.174 lines 1 and 2: 'connected type' should read 'adjoint type'.
