It is well known that for a given Riemannian manifold the representation of the restricted holonomy group on the tangent space is a direct product of a trivial representation and irreducible ones. By the author an analogous result was proved for the holonomy group of the normal connection of a submanifold of a space of constant curvature [see: The normal holonomy group, Proc. Am. Math. Soc. 110, No. 3, 813-818 (1990; Zbl 0708.53023)]. In this case the nontrivial factors are isotropy representations of simple Riemannian symmetric spaces. In the paper under review the following result is presented: Every irreducible isotropy representation of a simple Riemannian symmetric space of rank $$\geq 2$$ can arise in this way from an appropriate submanifold of a sphere with the possible exception of 10 representations which are listed. A detailed proof is given by E. Heintze and the author in Indiana Univ. Math. J. 41, No. 3, 869-874 (1992; Zbl 0759.53034).
