Abstract: Let $ \Lambda$ be a lattice in an $ n$-dimensional Euclidean space $ E$ and let $ \Lambda'$ be a Minkowskian sublattice of $ \Lambda$, that is, a sublattice having a basis made of representatives for the Minkowski successive minima of $ \Lambda$. We extend the classification of possible $ \mathbb{Z}/d\mathbb{Z}$-codes of the quotients $ \Lambda/\Lambda'$ to dimension $ 9$, where $ d\mathbb{Z}$ is the annihilator of $ \Lambda/\Lambda'$.
