Dear Forum,

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).
Features include

* construction of PBW-type bases,
* construction of irreducible modules,
* construction of elements of the canonical basis.

You can obtain it from

http://www.gap-system.org/Info4/deposit.html#pkg

or from

http://www.math.uu.nl/people/graaf/quagroup.html

I welcome any questions or comments.

Best wishes,

Willem de Graaf
