\(\operatorname {SL}(2,11)\) is \({\mathbb Q}\)-admissible
Let \(F\) be an algebraic number field. A field extension \(N\) of \(F\) is called \(F\)-adequate if it is the maximal subfield of a central division algebra over \(F\). A finite group is called \(F\)-admissible if it is the Galois group of an \(F\)-adequate Galois extension of \(F\). The author proves that the group \(\text{SL}(2,11)\) is admissible for the field of rational numbers.
