∀ {R : Type w₁} {A : Type w₂} {B : Type w₃} [inst : CommRing R] [inst_1 : CommRing A] [inst_2 : Algebra R A]
  [inst_3 : CommRing B] [inst_4 : Algebra R B] [Algebra.FinitePresentation R A] (e : A ≃ₐ[R] B),
  Algebra.FinitePresentation R B

If e : A ≃ₐ[R] B and A is finitely presented, then so is B.
