Extra info and code examples

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. This package contains the GAP compiler and the headers files and objects files necessary to build GAP packages. The GAP compiler (GAC) creates C code from GAP code and then calls the system's C compiler to produce machine code from it. This can result in a speedup.
