If you want to do anything serious you will need to add your own programs, but the package is a good start. A few years ago I did some quite interesting computation with it. The problem was to find five distinct elements of SO(3) (the group of rotations of the sphere) whose sum is 0. The explicit answer can be found using a bit of geometry and the Quaternions package, and makes a good exercise for those interested in such things ;-) Andrzej Kozlowski Chiba, Japan http://www.mimuw.edu.pl/~akoz/
