Abstract
Cohomogeneity one RiemannianG-manifolds (i.e. Riemannian manifolds with a groupG of isometries having an orbit of codimension one) are studied. A description of such manifolds (up to some normal equivalence) is given in terms of Lie subgroups of Lie groupG. The twist of a geodesic normal to all orbits is defined as the number of intersections with a singular orbit. It is equal to the order of some Weyl group, associated with theG-manifold. Some results about possible values of the twist are obtained.
