The inverse Galois problem asks whether every finite group is the Galois group of some extension of the rational numbers. In any given case, this amounts to finding a polynomial with prescribed symmetries. The aim of this problem is to find a polynomial whose Galois group is the Mathieu group \(M_{23}\). This is an especially interesting case because it is the last of the sporadic simple groups for which no such polynomial is known.

It is not guaranteed that such a polynomial must exist, but mathematicians generally expect it to.

Warm-up: we ask for a polynomial whose Galois group is the Mathieu group \(M_{22}\). Such constructions are well-known.
