1 Definition of a Group A group is a setG paired with a binary operation such that they satisfy the following: Associativity: Forx,y,zG, (xy)z=x (yz) Identity: eGsuch thatgG,eg=ge=g Inverses:gG,g 1 Gsuch thatgg 1 =g 1 g=e. In doing so he developed a new mathematical theory of symmetry, namely group theory. Basic Group Theory.
