On construit dans [R] des représentants explicites des fibrés principaux de fibre au-dessus de ; on en déduit des actions libres et explicites de , dont les quotients sont des sphères exotiques de dimension . La description de ces actions est basée sur une formule de classification des fibrés. Or cette formule est incorrecte. Le théorème 1 corrige cette formule ainsi que la formule de classification ; le théorème 2 exhibe les indices corrects des sphères exotiques de dimension qui apparaissent comme quotient des actions libres de .
In [R] explicit representatives for -principal bundles over are constructed, based on these constructions explicit free -actions on the total spaces are described, with quotients exotic -spheres. To describe these actions a classification formula for the bundles is used. This formula is not correct. In Theorem 1 below, we correct the classification formula and in Theorem 2 we exhibit the correct indices of the exotic -spheres that occur as quotients of the free -actions described above.
