Multi-dimensional cyclic code is a natural generalization of cyclic code. In an earlier paper we explored two-dimensional constacyclic codes over finite fields. Following the same technique, here we characterize the algebraic structure of multi-dimensional constacyclic codes, in particular three-dimensional (α,β,γ)- constacyclic codes of arbitrary length sℓ k and their duals over a finite field 𝔽_q, where α,β,γ are non zero elements of 𝔽_q. We give necessary and sufficient conditions for a three-dimensional (α,β,γ)- constacyclic code to be self-dual.
