10 Acknowledgement

We would like to thank the many people who have made contributions of various kinds to the development of GAP since 1986, in particular:

Isabel M. Araújo, Robert Arthur, Hans Ulrich Besche, Thomas Bischops, Oliver Bonten, Thomas Breuer, Frank Celler, Gene Cooperman, Bettina Eick, Volkmar Felsch, Franz Gähler, Greg Gamble, Willem de Graaf, Burkhard Höfling, Jens Hollmann, Derek Holt, Erzsébet Horváth, Alexander Hulpke, Ansgar Kaup, Susanne Keitemeier, Steve Linton, Frank Lübeck, Bohdan Majewski, Johannes Meier, Thomas Merkwitz, Wolfgang Merkwitz, James Mitchell, Jürgen Mnich, Robert F. Morse, Scott Murray, Joachim Neubüser, Max Neunhöffer, Werner Nickel, Alice Niemeyer, Dima Pasechnik, Götz Pfeiffer, Udo Polis, Ferenc Rákóczi, Sarah Rees, Edmund Robertson, Colva Roney-Dougal, Ute Schiffer, Jack Schmidt, Martin Schönert, Ákos Seress, Andrew Solomon, Heiko Theißen, Rob Wainwright, Alex Wegner, Chris Wensley and Charles Wright.

The following list gives the authors, indicated by A, who designed the code in the first place as well as the current maintainers, indicated by M of the various modules of which GAP is composed.

Since the process of modularization was started only recently, there might be omissions both in scope and in contributors. The compilers of the manual apologize for any such errors and promise to rectify them in future editions.
