A degree stable Lie algebra is defined in the paper of K-Bong Nam, and Seul Hee Choi [Degree Stable Lie Algebras I, Algebra Colloquium 13 (2006) 487--494]. The automorphism group AutLie(S+(2)) of the Lie algebra S+(2) and the automorphism group of the Lie algebra W(1,0,2) are also found in this paper. We find the algebra automorphism groups of the Lie algebras W(12,1,1) and W(12,2,0) in this work. We show that the Cartan subalgebras of W(12,1,1) and W(12,2,0) are one dimensional.
