• The identity element is always the only element in its class, that is • If is abelian then for all , i.e. for all (and the converse is also true: if all conjugacy classes are singletons then is abelian). • If two elements belong to the same conjugacy class (that is, if they are conjugate), then they have the same order. More generally, every statement about can be translated into a statement about because the map is an automorphism of called an inner … • The identity element is always the only element in its class, that is • If is abelian then for all , i.e. for all (and the converse is also true: if all conjugacy classes are singletons then is abelian). • If two elements belong to the same conjugacy class (that is, if they are conjugate), then they have the same order.

Yes, the orbits of a group action partition the space that the group is acting on. If that space is finite, then its cardinality is the sum of the cardinalities of the orbits. Moreover, you can indeed apply the orbit-stabilizer theorem to re-write the equation the way that you have. The class equation is just this observation applied ...
WebApr 8, 2024 · Given an action G × X → X of a group G on a set X, for every element x ∈ X, the stabilizer subgroup of x (also called the isotropy group of x) is the set of all elements in G that leave x fixed: StabG(x) = {g ∈ G ∣ g ∘ x = x}. If all stabilizer groups are trivial, then the action is called a free action. Homotopy-theoretic formulation
