Abelian obstructions in inverse Galois theory
2009We show that if a finite group G is the Galois group of a Galois cover of P1 over Q, then the orders pn of the abelianization of its p-Sylow subgroups are bounded in terms of their index m, of the branch point number r and the smallest prime ℓ ̸| |G| of good reduction of the branch divisor. This is a new constraint for the regular inverse Galois problem:

The Inverse Problem Of Galois Theory
In this survey we outline the milestones of the Inverse Problem of Galois theory historically up to the present time. We summarize as well the contribution of the authors to the Galois Embedding Problem, which is the most natural approach to the the Inverse Problem in the case of non-simple groups.Michailov, Ivo, Ziapkov, Nikola

On the general inverse problem of Galois theory
1986Summary: For a finite group \(G\) and a field \(K\) let \(\nu(G,K)\) be the number of non-\(K\)-isomorphic separable normal extensions of \(K\) with \(G\) as a Galois group. Some results are announced concerning the distribution of the values of \(\nu(G,K)\).
