The $\alpha\beta$-construction of magic hypercubes

Abstract

A magic hypercube of dimension $m$ and order $n$ is an $n^{m}$ array filled with $n^{m}$ distinct positive integers $1, 2, \dots, n^{m}$ such that the entries in each of the $m n^{m - 1}$ hyperrows and the $2^{m - 1}$ space diagonals sum to the same number, the magic sum. We present the $α β$ -construction which follows an algorithm which places entries into a hypercube by moving along permutations of the vector $⟨ α, 0, \dots, 0, β ⟩$ . Under certain restrictions, this construction creates odd-ordered magic hypercubes.
