Query: On the Lego-Teichmuller game   For a smooth oriented surface S, denote by M(S) the set of all ways to
represent S as a result of gluing together standard spheres with holes (``the
Lego game''). In this paper we give a full set of simple moves and relations
which turn M(S) into a connected and simply-connected 2-complex. Results of
this kind were first obtained by Moore and Seiberg, but their paper contains
serious gaps. Our proof is based on a different approach and is much more
rigorous.
