Changes in the GAP Character Table Library



This list contains the changes in the GAP character table library since the official upgrade for GAP 3.4 in October 1996. We denote mathematical errors by *** and new information by NEW. We use C to denote changes that are not obviously corrections; the number of these changes is kept small.
