We describe explicitly the group of transverse diffeomorphisms of several types of minimal linear foliations on the torus $T^n$, $n\ge 2$. We show in particular that non-quadratic foliations are rigid, in the sense that their only transverse diffeomorphisms are $\pm \mathrm{Id}$ and translations. The description derives from a general formula valid for the group of transverse diffeomorphisms of any minimal Lie foliation on a compact manifold. Our results generalize those of P. Donato and P. Iglesias for $T^2$, P. Iglesias and...
