Query: Lifting involutions in a Weyl group to the torus normalizer   Let N be the normalizer of a maximal torus T in a split reductive group over
F_q and let w be an involution in the Weyl group N/T. We construct explicitly a
lifting n of w in N such that the image of n under the Frobenius map is equal
to the inverse of n.
