GAP 4.10.1

For an overview of changes in GAP 4.10.1 see file.

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.

gap-4.10.1.tar.gz 378 MB sha256: b2d8800e338a6a9afdf92b06368c2e1a16b8adebffcd4c10319c1b3a4e827e45
gap-4.10.1.tar.bz2 310 MB sha256: 2038527a26f1c796cb6d6d54011b43a54de199ccfafd22a176817006f707da8c 408 MB sha256: aba51d885d12f7734dd63d00a62e38ab324d49adea0045157ebeb9778e67151c

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-4.10.1 (default), D:\gap-4.10.1 or C:\Math\GAP\gap-4.10.1, but you must not install it in a directory named like C:\Program files\gap-4.10.1 or C:\Users\alice\My Documents\gap-4.10.1 etc.

gap-4.10.1-p1.exe 455 MB sha256: 17085dc5d26f9100e980bdd6bb11e41fcbfb024843cd07b81241b38c17b4f767

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 technical 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: de67416e42ae110a7a8fc7db502efaf99d92a6dd0f61c1aa813725fb9cc9852e 496 MB sha256: 120521e679cffa5c039abd8dcfc6c618d04463f6aedd8f156680203698dadae9

In addition, there is an experimental 64-bit version of GAP for Windows here: 485 MB sha256: da4c4998c9e37ae041bd7cd634aa2553fa5b95a5e3c90d71eddcfa61adfa97fe
