It was brought to our attention that the transformation matrix from the cubic to crystallographic reference frame, Scryst = ^ R c S cubic , Eq. (43) of our work, used an unconventional orientation of the cubic axes triad, corresponding to x?-x and y?-y of the conventional choice for the cubic reference frame. While presumably leading to the same physical results, our transformation should have resulted in a model that is different from the extended Kitaev-Heisenberg model listed in Eq. (44) by more complicated sign conventions for the G and G' terms on different bonds. To adhere to the conventional and symmetric choice, the transformation matrix ^Rc in Eq. (43) should read as (Formula Presented) (Figure Presented).
