properties of this axiomatic characterisation (in spec folder) *)

(* A simple suffix array construction algorithm and its formal verification against the
specification (in simple folder).
This is used to validate the specification and to compare the verification effort to
that of verifying SAIS *)

array construction, we obtain a corollary stating that generalised SAIS is functionally
equivalent to the simple construction algorithm. *)
