Generalizing results of Morishita and Vogel, an explicit description of thetriple Massey product for the Galois group $G_S(2)$ of the maximal 2-extensionof $\mathbb{Q}$ unramified outside a finite set of prime numbers $S$ containing2 is given in terms of R\'edei symbols. We show that mild pro-2-groups withZassenhaus invariant 3 occur as Galois groups of the form $G_S(2)$.Furthermore, a non-analytic mild fab pro-2-group having only 3 generators isconstructed .
