Dear Algtop-list,

by Whitehead, a weak homotopy equivalence between connected Kan 
simplicial sets is a simplicial homotopy equivalence. Does there exist 
a construction (involving choices) of the inverse-up-to-homotopy?

(We are particularly interested in the case of a weak homotopy 
equivalence in the image of \bar W: simp. gps -> simp. sets.)

Best
