AbstractGiven a number field F and a finite abelian group G≅≎′,i(Z/n,Z), n1|n2|⋯|ni−1|ni, it is proven that there exists an extension K/F which is Galois and cogalois with Gal(K/F) ≅ cog(K/F) ≅ G iff the primitive n1 1-th roots of unity are present in F and the field obtained by adjoining the n1-th roots of unity to F is pure over F
