Abstract
Orbital period study using photoelectric times of minima of SW Lac reveals that the period change is caused by the orbital motion of a triple system around a fourth body. The orbital periods of the third and the fourth body are 19.67yr and 70.25 yr respectively, and their masses are close to 1 M⊙ each.
