Abstract
In Question 19.35 of the Kourovka Notebook, M. H. Hooshmand asks whether, given a finite group and a factorization , one can always find subsets of with such that equivalently, such that the group multiplication map is a bijection. We show that for the alternating group on 4 elements, , and , the answer is negative. We then generalize some of the tools used in our proof, and note an open question.
