Abstract: This paper deals with the question of when there exists on a Euclidean space a nontrivial probability measure $ \mu $ which is invariant under a group $ \Gamma $ of integer matrices. Necessary conditions on $ \Gamma $ and the dimension are discussed. It is shown that nontrivial examples do exist, but only in dimensions $ \geqslant 6$. In fact, the only explicit example given is in dimension 10.
