There was a small error in the Space group list poster, which was caused by a stupid ‘Copy&Paste’ mistake: The example of the crystal structure with the space group Fdd2 was labeled – as the example right above on the poster – with ‘Cobaltite’, but it has to be named, of course, ‘Edenharterite’ instead.
Thanks to Melanie Müller, who brought this error to my intention!
Furthermore, I decided to include the space group numbers on the poster in order to provide a better and faster ‘navigation’ of the viewers’ eye 🙂
The corrected version can be downloaded here!

Typo for no 2: chalcanthite, not chancalthite.
(Thank you for giving me the chance to even improve this great poster!)
Thank you very much! I’ve corrected the mistake now!
