Query: Divisibility of the stable Miller-Morita-Mumford classes   We determine the sublattice generated by the Miller-Morita-Mumford classes
$\kappa_i$ in the torsion free quotient of the integral cohomology ring of the
stable mapping class group. We further decide when the mod p reductions
$\kappa_i$ vanish.
