Maple script for Weyl group related computation

This script requires the “coxeter and weyl package” and "posets package" by J.Stembridge. Download the "Vanilla" editions from:

rename it to “coxeter.txt” and "posets.txt" and place in the same directory as the script file.

Download "traverse" example as well from below

and rename it to "traverse.txt"
