The generator matrix

 1  0  1  1  1  1
 0  1 2X+7 X+6 2X  8
 0  0  6  3  0  6

generates a code of length 6 over Z9[X]/(X^2+6,3X) who´s minimum homogenous weight is 9.

Homogenous weight enumerator: w(x)=1x^0+22x^9+378x^10+1008x^12+756x^13+18x^15+4x^18

The gray image is a code over GF(3) with n=54, k=7 and d=27.
