The canonical representation works by defining the basis vectors to have whatever inner products you want them to have in order to satisfy the Coxeter relationships you're given. You end up with a vector space and a metric, but the metric is presumably not going to have any nice properties.
So, I suppose I'd have to do something involving the Gram-Schmidt procedure to get an orthonormal basis in order to encode the reflections into matrices... -- Mike Stay - metaweta@gmail.com http://www.cs.auckland.ac.nz/~mike http://reperiendi.wordpress.com
