Group Theory in Mathematics Group theory is the study of a set of elements present in a group, in Maths. Our rst class of examples are groups of symmetry. In doing so he developed a new mathematical theory of symmetry, namely group theory. We call < fg: 2 Ig > the subgroup of G generated by fg: 2 Ig . 2. Normal .
