WebWe show that any quadratic extension of Hilbertian fields of characteristic different from 2 can be embedded in an S n -extension (i.e. a Galois extension with the symmetric group S n as Galois group). For n ≠6, it will follow that A n has the so-called GAR-property over any field of characteristic different from 2.
