Resumen

In this work codes over one of seven local Frobenius non–chain rings of order 16 are studied. The ring structure is discussed showing both the similarities and differences to a previously studied ring. A duality preserving Gray map is given and is used to present MacWilliams identities and self–dual codes. Connections between these self–dual codes and real unimodular lattices are also discussed. Some extremal Type II ℤ4–codes are provided as images of codes over this ring. ℤ4–codes that are images of linear codes over the studied ring are characterised through automorphism groups and some well–known families of ℤ4–codes (different versions of quaternary Reed–Muller codes) are proved to be linear over it.
