Dear Andrius, dear Robert!

thanks for taking care about this entry and for finding the coordinates!

The coordinates seem reasonable but the space group is definitely not P1
-- there are gaps in Al layers, and the structure clearly has at least a
3-fold axis (see attached screen-shots).

Robert, please do not use the COD entry 1010563 untill we fix the space
group (hopefully we do that today).

Regards,
Saulius
