The generator matrix

 1  0  1  1  1  0  2  2  4
 0  1  3  0  3  1  4  2  2
 0  0  4  4  0  4  4  4  4

generates a code of length 9 over Z8 who´s minimum homogenous weight is 8.

Homogenous weight enumerator: w(x)=1x^0+81x^8+24x^10+22x^12

The gray image is a code over GF(2) with n=36, k=7 and d=16.
