Abstract
A permutation of the point set of the affine space \({{\mathrm{AG}}}(n,q)\) is called an integral automorphism if it preserves the integral distance defined among the points. In this paper, we complete the classification of the integral automorphisms of \({{\mathrm{AG}}}(n,q)\) for \(n\ge 3\).
