The facts
Each one read from GAP's own pages, with the date it was checked.
What it does
- Data libraries
- GAP includes large data libraries of algebraic objects.checked 11 Oct 2026
- 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.checked 11 Oct 2026
- 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.checked 11 Oct 2026
- Jupyter integration
- The Francy package documentation says it supports Jupyter Lab and uses the JupyterKernel package to render GAP-generated graphics.checked 11 Oct 2026
- 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.checked 11 Oct 2026
- 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.checked 11 Oct 2026
- Mathematical scope
- The documentation describes support for structures including groups, semigroups and algebras.checked 11 Oct 2026
- 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.checked 11 Oct 2026
- Programming
- GAP includes a programming language and a library of thousands of functions implementing algebraic algorithms.checked 11 Oct 2026
- Purpose
- GAP is a free, open and extensible software package for computation in discrete abstract algebra, with particular emphasis on computational group theory.checked 11 Oct 2026
- Support
- The manual gives [email protected] as a contact address.checked 11 Oct 2026
Where it runs
- Platforms
- A GAP installation guide reproduced in the Singular package manual says GAP runs on Unix-like systems and recent Windows or macOS systems.checked 11 Oct 2026
