We show that there are O ε (H 1.5+ ε) monic, cubic polynomials with integer coefficients bounded by H in absolute value whose Galois group is A 3. We also show that the order of magnitude for D 4 quartics is H 2 (log H) 2, and that the respective counts for A 4, V 4, C 4 are O (H 2.91), O (H 2 log H), O (H 2 log H). Our work establishes that irreducible non-S 3 cubic polynomials are less numerous than reducible ones, and similarly in the quartic setting: these are the first two solved cases of a 1936 conjecture made by van der Waerden.
