We describe here two sets of generators of an ideal , of finite index inside the square of the augmentation ideal of , associated to the Dirichlet character of the finite group . That peculiar ideal first appeared in questions related to the computation of class number formulas for abelian non ramified extensions of -fields cf. [2] and [3], satisfying certain special conditions which are outlined in the introduction of [1]. A rough idea of these formulas is given in §§2 and...
