How To Install gap-aclib on Ubuntu 22.04
Introduction
In this tutorial we learn how to install gap-aclib
on Ubuntu 22.04.
What is gap-aclib
gap-aclib is:
GAP is a system for computational discrete algebra, with particular emphasis on Computational Group Theory. GAP provides a programming language, a library of thousands of functions implementing algebraic algorithms written in the GAP language as well as large data libraries of algebraic objects. GAP is used in research and teaching for studying groups and their representations, rings, vector spaces, algebras, combinatorial structures, and more.
The AClib package contains a library of almost crystallographic groups and a some algorithms to compute with these groups. A group is called almost crystallographic if it is finitely generated nilpotent-by-finite and has no non-trivial finite normal subgroups. Further, an almost crystallographic group is called almost Bieberbach if it is torsion-free. The almost crystallographic groups of Hirsch length 3 and a part of the almost cyrstallographic groups of Hirsch length 4 have been classified by Dekimpe. This classification includes all almost Bieberbach groups of Hirsch lengths 3 or 4. The AClib package gives access to this classification; that is, the package contains this library of groups in a computationally useful form. The groups in this library are available in two different representations. First, each of the groups of Hirsch length 3 or 4 has a rational matrix representation of dimension 4 or 5, respectively, and such representations are available in this package. Secondly, all the groups in this libraray are (infinite) polycyclic groups and the package also incorporates polycyclic presentations for them. The polycyclic presentations can be used to compute with the given groups using the methods of the Polycyclic package. The package was written by Karel Dekimpe and Bettina Eick.
There are three methods to install gap-aclib
on Ubuntu 22.04. We can use apt-get
, apt
and aptitude
. In the following sections we will describe each method. You can choose one of them.
Install gap-aclib Using apt-get
Update apt database with apt-get
using the following command.
sudo apt-get update
After updating apt database, We can install gap-aclib
using apt-get
by running the following command:
sudo apt-get -y install gap-aclib
Install gap-aclib Using apt
Update apt database with apt
using the following command.
sudo apt update
After updating apt database, We can install gap-aclib
using apt
by running the following command:
sudo apt -y install gap-aclib
Install gap-aclib Using aptitude
If you want to follow this method, you might need to install aptitude first since aptitude is usually not installed by default on Ubuntu. Update apt database with aptitude
using the following command.
sudo aptitude update
After updating apt database, We can install gap-aclib
using aptitude
by running the following command:
sudo aptitude -y install gap-aclib
How To Uninstall gap-aclib on Ubuntu 22.04
To uninstall only the gap-aclib
package we can use the following command:
sudo apt-get remove gap-aclib
Uninstall gap-aclib And Its Dependencies
To uninstall gap-aclib
and its dependencies that are no longer needed by Ubuntu 22.04, we can use the command below:
sudo apt-get -y autoremove gap-aclib
Remove gap-aclib Configurations and Data
To remove gap-aclib
configuration and data from Ubuntu 22.04 we can use the following command:
sudo apt-get -y purge gap-aclib
Remove gap-aclib configuration, data, and all of its dependencies
We can use the following command to remove gap-aclib
configurations, data and all of its dependencies, we can use the following command:
sudo apt-get -y autoremove --purge gap-aclib
