Abstract
We prove that the Hurwitz action on reflection factorizations of Coxeter elements is transitive up to certain natural constraints in the complex reflection groups G4 and G5. This affirms a more general conjecture by Lewis and Reiner in these specific cases. The proof uses induction on length of the factorization using the fact that the square of a reflection is also a reflection.
