Specifically, the bijection is given by hGx ↦ h·x. This result is known as the orbit-stabilizer theorem. If G and X are finite then the orbit-stabilizer theorem, together with Lagrange's theorem, gives This result is especially useful since it can be employed for counting arguments. Note that if two elements x and y belong to the same orbit, then their stabilizer subgroups, Gx and Gy, are conjugate (in particular, they are isomorphic). More precisely: if y = g·x, then Gy = gGx g−1. Points with conjugate stabilizer subgroups are said to have the same orbit-type.

As these two prototypes are both abelian, so is any cyclic group. The study of abelian groups is quite mature, including the fundamental theorem of finitely generated abelian groups; and reflecting this state of affairs, many group-related notions, such as center and commutator, describe the extent to which a given group is not abelian. Symmetry groups Symmetry groups are groups consisting of symmetries of given mathematical objects—be they of geometric nature, such as the introductory symmetry group of the square, or of algebraic nature, such as polynomial equations and their solutions.

The most basic examples are the reals R under addition, (R \ {0}, ·), and similarly with any other topological field such as the complex numbers or p-adic numbers. All of these groups are locally compact, so they have Haar measures and can be studied via harmonic analysis. The former offer an abstract formalism of invariant integrals. Invariance means, in the case of real numbers for example: for any constant c. Matrix groups over these fields fall under this regime, as do adele rings and adelic algebraic groups, which are basic to number theory.
