The question of whether a given subspace of \(\mathbb {Q}^d\) can be reached from a starting vector using linear transformations from a given finite set is well known to be undecidable in dimension 3 and above. We show that, in contrast, the invariance problem, i.e. the question of whether it is possible to remain inside a given subspace indefinitely using linear transformations from a given finite set, is decidable.
