The generator matrix

 1  0  1  6  1 12  1 10  4
 0  1  6  1 12  1 10  1 12
 0  0  8  8  8  8  0  0  0

generates a code of length 9 over Z16 who´s minimum homogenous weight is 8.

Homogenous weight enumerator: w(x)=1x^0+270x^8+224x^10+16x^12+1x^16

The gray image is a code over GF(2) with n=72, k=9 and d=32.
