The generator matrix

 1  0  1  1  1  1  1  1  1
 0  1  1  2 3X+4  0  X 3X+1 3X+1
 0  0 3X 2X  X  X 3X 2X 4X

generates a code of length 9 over Z5[X]/(X^2) who´s minimum homogenous weight is 29.

Homogenous weight enumerator: w(x)=1x^0+120x^29+32x^30+300x^32+360x^34+48x^35+500x^36+1200x^37+520x^39+24x^40+20x^45

The gray image is a linear code over GF(5) with n=45, k=5 and d=29.
