It is proved that strong exact Borel subalgebras of quasi-hereditary algebra are conjugate to each other and are in bijection with the collection of maximal semisimple subalgebras.

We provide an explicit bijection between the ad-nilpotent ideals of a Borel subalgebra of a simple Lie algebra g and the orbits of Q/(h + 1) Q under the Weyl group ( Q being the coroot lattice and h the Coxeter number of g). From this result we deduce in a uniform way a counting formula for the ad-n
