The generator matrix

 1  0  0  1  1  1 X^3+X  1  1
 0  1  0  X X^2+1 X^2+X+1  1 X^2+X X^2
 0  0  1  1 X+1  X X^2+1 X^3+X^2+X+1 X^2

generates a code of length 9 over Z2[X]/(X^4) who´s minimum homogenous weight is 6.

Homogenous weight enumerator: w(x)=1x^0+26x^6+292x^7+785x^8+1916x^9+748x^10+284x^11+38x^12+4x^13+2x^14
