While checking self rotation functions is a great idea, I would shy away 
from such categorical assertions as self rotation functions are not 
always cleanly interpretable (despite GLRF, which is my favorite as 
well), and an eight-fold NCS might not be due to an eight-fold rotation: 
you can have eight molecules with different arrangements (such as two C4 
"tetramers") as well as with improper NCS, or through translational NCS 
as well.
