GAP 3 Data Library "Character Tables"

Relation to the corresponding GAP 4 data library

The GAP 4 Data Library Character Tables is a considerable extension of the GAP 3 library and technically has become a GAP 4 package. All GAP 3 functions involving characters will work with this GAP 4 library (see the home page The GAP Character Table Library for details).


All character tables in the ATLAS and the Modular ATLAS with many additions.


Thomas Breuer and many other people.
