Cayley Diagrams of Small Groups, drawn on the Torus

This page gives the Cayley diagrams of all the groups of order less than 32. Their presentations are also given. The letters in the presentations correspond to the colours in the Cayley diagrams: black red green blue mauve grey.

The pink lines and arrows at the edges of each diagram are sewing instructions, and the light pink region outside these lines is not really there. If the previous sentence makes no sense to you, the Wikipedia page on Fundamental polygon may help.

Notation

N ⋊ H indicates a semidirect product of N by H. N is the normal subgroup.

QN, DN and DicN denote groups of order N (the quaternion, dihedral and dicyclic groups respectively).

Cyclic groups are denoted by C.
