Working with Generating Functions, some initial terms, we can progressively calculate more. We have also developed a way to convert some recurrence relations into a generating function. If we can manipulate the generating function and then expand it as a power series that enables us to give explicit expressions for the count by read

Permutation Groups,umber of arrangements of a set of objects, we might wish to count two arrangements which are symmetrical as being the same. A simple example is that of a bracelet made up of different coloured beads. It then makes sense to count two arrangements of the beads as the same if one can be rotated into th

Group Actions and Counting,e introduced the idea of a group action and the orbits of this action. This is going to be crucial to the development. Roughly we have an object which we are going to “colour” and we find the number of ways we can do this if we allow for the symmetries of the object.

Graphs,the word graph represents a collection of vertices and of edges. They are usually shown as very simple pictures, where the vertices are represented by dots and edges by lines..We begin by drawing some simple graphs – see Figure 8.1. Then we will give a more formal definition of what we mean. We go on to count various classes of graphs.
