We present a new construction of four dimensional \( \mathcal{N}=3 \) theories, given by M5 branes wrapping a T 2 in an M-theory U-fold background. The resulting setup generalizes the one used in the usual class \( \mathcal{S} \) construction of four dimensional theories by using an extra discrete symmetry on the M5 worldvolume. Together with the M-theory U-fold description of (0...
