The Galois group of the cyclotomic field of order n over F of characteristic 0 is abelian.
Every algebra consists of a set and certain operations on that set. An operation is a way of combining any two members of a set to produce a unique third member of the same set.
An algebraic structure is an arbitrary set, with one or more operations defined on it.
Algebra is the study of algebraic structures.
