ModIsom is a GAP4 package. It contains various methods for computing with nilpotent associative algebras. In particular, it contains a method to determine the automorphism group and to test isomorphis of such algebras over finite fields and of modular group algebras of finite p-groups, and it contains a nilpotent quotient algorithm for finitely presented associative algebras and a method to determine Kurosh algebras.
To install the package ModIsom move the file modisom-X.Y.Z.tar.gz
(or any other archive containing it) into the pkg
directory.
Usually this will be the pkg
subdirectory in your GAP4 installation.
However, it is also possible to have a pkg
subdirectory in a different
place, see the section Installing GAP Packages
of the GAP4 reference
manual for more information. Then simply unpack modisom-XX.tar.gz
and
your installation is complete. To load the package, call
gap> LoadPackage( "modisom" );
The manual of ModIsom is contained in modisom/doc
and modisom/htm
directories.
