We consider the problem of determining, for a given family of Galois extensions N l K with Galois group A9 their relative Galois module structure, that is, the ring of integers ON s module over the group ring OKA. In order to get a grip on this problem we ask and answer here in a number of cases first the possibly more restricted question: what, if anything, obstructs the Galois modules from being free? The answer is: complex conjugation.
