<Discontinued> Catalogue of Algebraic Systems/Groups of Small Order  <Discontinued>

The original Catalogue of Algebraic Systems was written by John Pedersen. John moved and I inherited it. The catalogue was quite incomplete.  It had a few mistakes in it and keeping it up was too much trouble. Meanwhile much more material on algebraic systems has appeared on the web.  For example, try Wikipeida, MathWorld, or PlanetMath .
