GAP 4.10.2

This release replaces GAP 4.10.1 (see the overview of changes between GAP 4.10.2 and GAP 4.10.1 here).

Linux and OS X

Download one of the archives below, unpack it and run ./configure; make in the unpacked directory. Then change to the pkg subdirectory and call ../bin/ to run the script which will build most of the packages that require compilation (provided sufficiently many libraries, headers and tools are available). For further details, see here. Expert users can find the description of all installation options in the file.

You may also consider one of the alternative distributions. Note, however, that these are updated independently and may not yet provide the latest GAP release.


We strongly recommend to use the .exe installer which contains binaries for GAP (compiled with the support of GMP and readline libraries) and for selected GAP packages, and provides the standard installation procedure. Note that the path to the GAP directory should not contain spaces. For example, you may install it in C:\gap-4.10.2 (default), D:\gap-4.10.2 or C:\Math\GAP\gap-4.10.2, but you must not install it in a directory named like C:\Program files\gap-4.10.2 or C:\Users\alice\My Documents\gap-4.10.2 etc.

The .exe installer should work for the majority of users. Alternatively (for example, if you don't have administrator's privileges on your Windows computer), you may use the archive and edit .bat files manually following instructions from the file. Furthermore, in case of techinical problems with readline support under Windows (e.g. command line editing doesn't work, or GAP crashes at startup), we recommend to try the archive. 496 MB sha256: 489ef34be4b1c072a9bf36a0d1631915688f636ac871ba46e08cad8d709d2a41 496 MB sha256: 49e783877e0dd07bf400e35b6bb99dbdcb43631cb3fccc414e2b4e8f28e53725

In addition, there is an experimental 64-bit version of GAP for Windows here: 570 MB sha256: d8fe324562b64395cfe45180404b5187b40353eb2d3e7dcfdbebadfd4ba44fe5
