<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, orPlanetMath .
