The generator matrix

 1  1  1  1  1  1  1  1 2X+2
 0  2  0  2  0 2X  2 2X+2 2X
 0  0 2X  0  0 2X 2X 2X  0
 0  0  0 2X 2X 2X 2X  0  0

generates a code of length 9 over Z4[X]/(X^2+2X+2) who´s minimum homogenous weight is 8.

Homogenous weight enumerator: w(x)=1x^0+78x^8+128x^9+32x^10+16x^12+1x^16

The gray image is a code over GF(2) with n=72, k=8 and d=32.
