The generator matrix

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

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

Homogenous weight enumerator: w(x)=1x^0+3x^8+22x^9+4x^10+2x^13

The gray image is a code over GF(2) with n=36, k=5 and d=16.
