论文摘要
我们通过表明Mathieu组$ M_ {22} $的全覆盖组及其自动形态组$ aut（M_ {22}）$的全部覆盖群来缩小文献差距。
We close a gap in the literature by showing that the full covering groups of the Mathieu group $M_{22}$ and of its automorphism group $Aut(M_{22})$ occur as the Galois group of $\mathbb{Q}$-regular Galois extensions of $\mathbb{Q}(t)$.
