A completely irregular figure has a symmetry group of order 1. The group of order 2 arises when the figure has bilateral symmetry, or when it is transformed into itself by a half-turn (i.e., rotation through two right angles).

Crisis in the French Labour Movementverted this method into an almost mechanical technique, a useful tool with a wide range of applications. In § 2.1 we apply it to determine an abstract definition for a given finite group. In § 2.4 we use it to find whether a given subgroup of an abstract group is normal. Finally, in § 2.5 we see how
