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

http://www-gap.dcs.st-and.ac.uk/~gap/Info4/share.html

and mirrors give more information and instructions for obtaining this
and other packages.
