Some finite abelian group (here ℤ𝑛) assumes as double role: (1) as a discrete configuration space for a system S, (2) as a translation group on that configuration space. We considered internal quantum reference frames associated with such finite groups and derived a number or properties. For example, we showed that gauge-invariant states (living in the trivial representation of the group) comprise the maximal subspace of states of S that admit frame-independent purifications.
