The generator matrix

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

generates a code of length 11 over Z4[X]/(X^2+2,2X) who´s minimum homogenous weight is 10.

Homogenous weight enumerator: w(x)=1x^0+14x^10+32x^11+15x^12+1x^14+1x^18

The gray image is a code over GF(2) with n=44, k=6 and d=20.
