The generator matrix

 1  0  1  1  1  6  2  2  1
 0  1  1  6  7  1  4  4  4
 0  0  2  0  6  4  2  2  4
 0  0  0  4  4  4  0  4  0

generates a code of length 9 over Z8 who´s minimum homogenous weight is 6.

Homogenous weight enumerator: w(x)=1x^0+30x^6+48x^7+161x^8+32x^9+161x^10+48x^11+30x^12+1x^18

The gray image is a code over GF(2) with n=36, k=9 and d=12.
