0 X X^2+2 X^2+X 2 X^2+X+2 X^2 X+2 X^2+X X X+2 X X^2+X+2 X X X 0 X^2+2 2
generates a code of length 19 over Z4[X]/(X^3+2,2X) who´s minimum homogenous weight is 18.
Homogenous weight enumerator: w(x)=1x^0+6x^18+112x^19+6x^20+1x^22+1x^24+1x^30
The gray image is a code over GF(2) with n=152, k=7 and d=72.
