    The illustration shows a #216 crystal, nope? The crystal contains mirror planes, but in group #196 you should not have any.

      Dear Tomas,

      I just checked the structure and although the original data set (and the CIF) was published as F23 your are right, the coordinate set of ZnSO4 shows clearly F-43m symmetry (#216 as you said)! Therefore, I will inform the FIZ Karlsruhe (editor of the ICSD) of the wrong data, will look for another compound, which truly shows F23 symmetry and will update the entry #196 of this space group list soon!

      thanks again and all the best
      Frank
