With this message I would like to draw your attention to a GAP4.3
package called QuaGroup, that I have written, for dealing with quantum
groups (quantized enveloping algebras of semisimple Lie algebras).
* construction of PBW-type bases,
* construction of irreducible modules,
* construction of elements of the canonical basis.
You can obtain it from
I welcome any questions or comments.
