On the ternary extended perfect Golay code by the modified GC-construction

It is shown that the ternary extended perfect Golay [12, 6, 6]_3-code can be constructed by the modified GC-construction. For the binary Golay [24, 12, 8]-code this has been shown by us earlier. In particular, the Golay [12, 6, 6]_3-code can be constructed using the GC-construction with the inner codes of length 3 and the outer codes of length 4.
