Abstract
Integral lattices invariant under the affine group AGLm (pt) in its natural permutation module Λ of dimension n = mt are studied. A complete description of such lattices is given. As a consequence we have results on automorphism groups of affine invariant codes over fields and finite residue rings ℤ/pkℤ.
