The generator matrix

 1  1  1  1  1  1  1  1  1  3  3  3  1  1
 0  3  0  3  0  3  6  6  6  0  3  3  0  3
 0  0  3  6  6  3  0  3  6  3  6  3  0  0

generates a code of length 14 over Z9 who´s minimum homogenous weight is 25.

Homogenous weight enumerator: w(x)=1x^0+18x^25+14x^27+18x^28+6x^30+18x^31+6x^33

The gray image is a code over GF(3) with n=42, k=4 and d=25.
