# Cayley Diagrams of Small Groups

This page gives the Cayley diagrams, also known as Cayley graphs, of all 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.

### 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.

Here are three ways of drawing a Cayley diagram for D14. The first one I regard as usefully reflecting the structure of the group. The other two are given to show that it is possible to draw them like this, and omitted for other dihedral groups.

Compare this diagram with those for D16, "Modular", and "Quasidihedral" below. These four diagrams show C2 acting in all four possible ways on C8, whose automorphism group is C2×C2.

The C2 acts on the D8 by the permutation (b,aab),(ab,aaab).

The upper diagram may make it clearer what happens: there are two black-and-red D8s, with the inner square of one rotated through π relative to the other. The lower diagram is prettier, having some of the symmetry of a cube.

There is little interest in Cayley diagrams of direct products. This one is like a man who walks round in circles (black), and takes his hat on and off (red). The hat does not affect the walking, and the walking does not affect the hat.
