GAP

Free plan

What the maker publishes

Data libraries

GAP includes large data libraries of algebraic objects. source

Extensibility

Users can write programs in the GAP language and use them like programs in the system library; contributed functionality is also provided through independently developed GAP packages. source

Installation limits

The installation guide says Unix users compile GAP, while compiled executables for Windows and Mac are included in the archives; some packages need additional installation for full functionality on Unix. source

Jupyter integration

The Francy package documentation says it supports Jupyter Lab and uses the JupyterKernel package to render GAP-generated graphics. source

Jupyter limitation

Francy's documentation says it is currently supported only on Jupyter Lab; for older Jupyter Notebooks it specifies installing Francy version 1.2.4. source

License

GAP is distributed under the GNU General Public License, version 2 or, at the recipient’s option, any later version; modifications may be redistributed but proprietary modifications are not allowed. source

Mathematical scope

The documentation describes support for structures including groups, semigroups and algebras. source

Package installation

The PackageManager documentation says GAP can download and install a package from its name, an archive URL, a Git repository URL, or a PackageInfo.g URL. source

Platforms

A GAP installation guide reproduced in the Singular package manual says GAP runs on Unix-like systems and recent Windows or macOS systems. source

Programming

GAP includes a programming language and a library of thousands of functions implementing algebraic algorithms. source

Purpose

GAP is a free, open and extensible software package for computation in discrete abstract algebra, with particular emphasis on computational group theory. source

Support

The manual gives [email protected] as a contact address. source
