Schönert M., Besche H.U., Breuer T. GAP Groups, Algorithms and Programming. Version 3, release 4

Aachen: Die Rheinisch-Westfälische Technische Hochschule (RWTH), 1995. — 1570 p.Schönert M., Besche H.U., Breuer T., Celler F., Eick B., Felsch V., Hulpke A., Mnich J., Nickel W., Pfeiffer G., Polis U., Theißen H.Welcome to the first release of GAP from St Andrews. In the two years since the release of GAP 3.4.3, most of the efforts of the GAP team in Aachen have been devoted to the forth-coming major release, GAP 4.1, which will feature a re-engineered kernel with many extra facilities, a completely new scheme for structuring the library, many new and enhanced algorithms and algorithms for new structures such as algebras and semigroups.While this was going on, however, our users were not idle, and several bugs and blemishes in the system were found, while a substantial number of new or improved share packages have been submitted and accepted. Once it was decided that the computational algebra group at St Andrews would take over GAP development, we agreed, as a learning exercise, to release a new upgrade of GAP 3.4, incorporating the bug fixes and new packages.
