To introduce students to the basic ideas of group theory.
The course introduces the axioms of a group. The main emphasis is on finite groups. We introduce the concept of isomorphism of groups and classify groups of small order up to isomorphism, introducing the necessary tools as we go along: Basic properties of inverse elements, subgroups, powers of elements, element orders, cyclic groups, cosets, Lagrange's Theorem, Cartesian products, conjugacy classes, the class equation, homomorphisms, and the Isomorphism Theorem.
There will be many examples of groups of symmetries, numbers, matrices, and permutations. In particular, symmetric and alternating groups will be introduced and studied. We will show cycle decomposition and sign of permutations.
We will also introduce group actions and show how they can be used for counting arguments.

Lectures are used for the delivery of theory and explanation of methods, illustrated with examples, and for giving general feedback on marked work. Problem Classes are used to help develop the students’ abilities at applying the theory to solving problems. Drop-ins are used to identify and resolve specific queries raised by students and to allow students to receive individual feedback on marked work. Office hours provide an opportunity for more direct contact between individual students and the lecturer.
The format of resits will be determined by the Board of Examiners

A substantial formal unseen examination is appropriate for the assessment of the material in this module. Written assignments (approximately 5 pieces of work of approximately equal weight) allow the students to develop their problem solving techniques, to practise the methods learnt in the module, to assess their progress and to receive feedback; this is thus formative as well as summative assessment.
