Measurements and calculations of magnetotransport in the organic conductor $(\mathrm{DMET}{)}_2{\mathrm{I}}_3$ detect and simulate all angular magnetoresistance oscillations known for quasi-one-dimensional conductors. By employing the actual triclinic crystal structure in the calculations, these results address the putative vanishing of the primary magnetoresistance phenomenon, the Lebed magic angle effect, for orientations in which it was expected to be strongest. They also show a common origin for Lebed and the so-called Lee-Naughton oscillations and confirm the generalized nature of angular effects in such systems.
