engineering.purdue.eduA FINITE FIELD? We do know that GF(23) is an abelian group because of the operation of polynomial addition satisfies all of the requirements on a group operator and because polynomial addition is commutative. [Every polynomial in GF(23) is its own additive inverse because of how the two numbers in GF(2) behave with respect to modulo 2 addition.]
