摘要：
In this note we introduce and prove a wide generalization and sharpening of Ihara's question/Oda-Matsumoto conjecture, for short I/OM. That leads to a quite concrete topological/combinatorial description of absolute Galois groups, in particular of Gal(Q)=Aut((Q) over bar), as envisioned by Grothendieck in his Esquisse d'un Programme.
