Dear GAP Forum members,
it is a pleasure to announce the acceptance of the GAP 4 package LAGUNA written by Victor Bovdi, Alexander Konovalov, Richard Rossmanith and Csaba Schneider.
LAGUNA provides a very welcome extension of the GAP-functionality
for calculations in modular group algebras. In particular there are
programs to compute the unit group of a modular group algebra of
a finite p-group. Furthermore certain properties of the Lie algebra
of a group algebra can be decided. LAGUNA is a substantial extension
of the former LAG-package, which it now fully replaces. It is
designed for GAP 4.3 (bugfix 4).
The GAP4 packages web page
and mirrors give more information and instructions for obtaining this
and other packages.
