Revisiting 3-Sasakian and $G_2$-structures

The algebra of exterior differential forms on a regular 3-Sasakian 7-manifold is investigated, with special reference to nearly-parallel $G_{2}$ 3-forms. This is applied to the study of 3-forms invariant under cohomogeneity-one actions by $S O (4)$ on the 7-sphere and on Berger’s space $S O (5) / S O (3)$ .
