Abstract
The family of all three-dimensional almost f-algebras, d-algebras, and f-algebras is constructed. It is shown that it contains all three-dimensional directly indecomposable ℓ-algebras. Also, a list of representatives of (algebraic) isomorphism classes of all three-dimensional algebras that can be ordered as an almost f-algebra, a d-algebra, or an f-algebra is given.
