Abstract
We consider manifolds of oriented flags SO(n)/SO(2)×SO(n−3)(n≥4)
as 4- and 6-symmetric spaces and
indicate characteristic conditions for invariant Riemannian
metrics under which the canonical f-structures on these
homogeneous Φ-spaces belong to the classes Kill f, NKf, and G1f of
generalized Hermitian geometry.
