In the late nineteen sixties it was observed that the r.e. languages form an infinite proper hierarchy based on the size of the Turing machines that accept them. We examine the fundamental position of the finite languages and their complements in the hierarchy and bring new results improving the previously known results. Some proofs make use of several auxiliary results for Turing machines with advice.
