a Definition 4: Let be a homomorphism from|S;]to[T;● is called an isomorphism if p is also one-to-one correspondence. We say that two algebraic systems [S; and t; o are isomorphism, if there exists an isomorphic function. We denoted by s; =T; I(S=T) Definition 4: Let  be a homomorphism from [S;*] to [T;•].  is called an isomorphism if  is also one-to-one correspondence. We say that two algebraic systems [S;*] and [T;•] are isomorphism, if there exists an isomorphic function. We denoted by [S;*][T;•](ST)
