A main result of this note is that every ∧-module with a free underlying abelian group decomposes into a direct sum of copies of the well-known indecomposable ∧-lattices of finiteOn infinite rank integral representations of groups and orders of finite lattice type200410.1007/s00013-004-1074-32015-12-12
