Abstract
We study Riemannian 8-manifolds with an infinitesimal action of SO(3) under which each tangent space breaks into irreducible spaces of dimensions 3 and 5. The relationship with quaternionic, almost product- and PSU-geometry is thoroughly explained using representation-theoretical arguments. This leads to the precise study of the intrinsic invariants upon which the structure depends, and also to the description of topological constraints for the existence of such manifolds. Finally, many examples are provided together with general recipes to build them.
