 Remove or change de link? 

The link to the german WP article Irrgarten might be misleading. The authors understand the article as purely garden-related, i.e. it only deals with botanical maze-like arrangements. Any reference to other representations (especially the mathematical stuff) seems to be very unwelcome there and are removed almost immediately. I have also doubts that ""irrgarten"" is equivalent to ""maze"". In german popular language, most people use the term ""labyrinth"" that, in modern times, seems to be almost equivalent to ""maze"". But maybe there is no fully equivalent German translation of ""maze"". Therefore I recommend removing the link to the German article. "
