The generator matrix

 1  1  1  1  1  1  1  X  X  1
 0  3  6  0  3  6  0  3  6  3

generates a code of length 10 over Z9[X]/(X^2+6,3X) who´s minimum homogenous weight is 19.

Homogenous weight enumerator: w(x)=1x^0+12x^19+54x^20+4x^21+6x^22+4x^24

The gray image is a code over GF(3) with n=90, k=4 and d=57.
