We recall the notation and results of [3].Let Q be the rational numbers.We let L be ais a finite Abelian group, and we letTV^ be the exponent of L*(Q)/L> i-e. the smallest positive integer x so that x • £ G Z, for all £ G LjjQ).Choosing a Z-basis -STj of L, we let DQ^L) =: det{Q(Jf/, Jfy)}.Then the integer DQ(L) is independent of the choice of basis of L.Then we define
