Abstract
Some results of Kéri and Östergård [3] regarding mixed binary/ternary covering codes are extended a) for mixed binary/ternary/quaternary codes, b) for codes in arbitrary mixed Hamming spaces. Some other results (sufficient conditions and examples of solved and unsolved cases) regarding 5-word codes in
Z2bZ3tZ4q
and
Z2bZ3tZ4qZ5f
are also provided in the paper.
