The generator matrix

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

generates a code of length 10 over Z4[X]/(X^2+2) who´s minimum homogenous weight is 7.

Homogenous weight enumerator: w(x)=1x^0+36x^7+322x^8+796x^9+1823x^10+750x^11+309x^12+48x^13+9x^14+2x^15
