This is a corrected version of my paper published in Journal of Geometry and Physics 25(1998), 205-226. I added missing cases to the classification theorem 1.1, namely the SO(n + 1)-manifold SO(n + 2)/(SO(n) × SO(2)), the SO(3)-manifold CP 2 and the SU(3)-manifold CP 1 × CP . Preface Christopher T. Woodward, in his review MR1619843 in MathSciNet, pointed out a gap in the classification of compa...
