FORMULA

Comment from Philippe Flajolet (Philippe.Flajolet(AT)inria.fr), Sep 06 2008: This sequence grows asymptotically roughly like exp(log(n)^2), but with a complicated pattern of oscillations: see the article by Dumas-Flajolet, page 4, for a complete expansion that is related to A000123 and methods of de Bruijn.
