<blockquote> <p><strong>Possible Duplicate:</strong><br> <a href="http://mathoverflow.net/questions/6781/ade-type-dynkin-diagrams" rel="nofollow">ADE type Dynkin diagrams </a> </p> </blockquote> <p>What is your favorite ADE-style classification? Here ADE style is to be understood in a very broad sense. A classification which is not precisely ADE, but roughly related is fine. For example simple complex Lie algebras, or affine Weyl groups would be okay.</p>
