We show that although the crystalline structure of Strontium Dithionate Tetrahydrate can be well described in either P64 and P31 space groups (or respectively, P62 and P32) and electro-optic measurements have indicated the 32 point group, optical second harmonic measurements performed on an oriented crystal are only compatible with point group 3.
