Bettina Eick

My research is connected to the development of practical algorithms for group theoretic problems. I am an author of the computer algebra system Gap and this page gives access to my external Gap packages.

All of my packages are written in GAP code. Except for the small groups library, they can be installed in the standard way in the pkg directory of GAP as described in the GAP manual or on my installation page.

Most of my packages are refereed GAP packages and hence they are also available with the GAP distribution and from the GAP web page. In this case a link to the GAP web page is included below. Note that this page is likely to contain the most recent version of the packages.
