Coxeter Group
A group generated by the elements 
for 
, ..., 
subject to
where
are the elements of a Coxeter Matrix. Coxeter used the Notation 
for theCoxeter group generated by the nodes of a Y-shaped Coxeter-Dynkin Diagram whose three arms have 
, 
, and
Edges. A Coxeter group of this form is finite Iff
