Basic knowledge mathematics
The composition of two symmetries (of an object or a physical theory) is again a symmetry. This gives a multiplication law on the symmetries which we call a group structure. In this course you will learn to work with such group structures, in particular finite groups such as the group of all rotation-symmetries of a spatial figure and permutation groups. You learn divisibility properties for elements and subgroups, you understand quotient groups with respect to a normal subgroup as well as the important classification result of finite rotation groups in three dimensions.
