Finite dimensional factor algebras of F_2[X_1,...,X_n] and their fixed   point subalgebras
  Fixed point subalgebras of finite dimensional factor algebras of algebras of polynomials in n indeterminates over the finite field $\mathbb F_2$ (with respect to all $\mathbb F_2$-algebra automorphisms) are fully described.
