Abstract
Graphs which generalize the simple or affine Dynkin diagrams are introduced. Each diagram defines a bilinear form on a root system and thus a reflection group. We present some properties of these groups and of their natural “Coxeter element.” The folding of these graphs and groups is also discussed, using the theory of C-algebras.
