Galois theory - Wikipedia
https://en.wikipedia.org/wiki/Galois_theory
WEBIn mathematics, Galois theory, originally introduced by Évariste Galois, provides a connection between field theory and group theory. This connection, the fundamental theorem of Galois theory, allows reducing certain problems in field theory to group theory, which makes them simpler and easier to understand.

WEBA Galois field is a finite field named in honor of Évariste Galois , one of the fathers of group theory. A field is a set that is closed under addition, subtraction, multiplication, and division. To be closed under an operation means that performing the operation on any two elements of the set will result in another element from the set.
