Abstract
We investigate the Galois group of the maximal -extension unramified outside a finite set of primes of a number field in the (tame) case, when no prime dividing is in . We show that the cohomology of is 'often' isomorphic to the étale cohomology of the scheme , in particular, is of cohomological dimension 2 then.
