The generator matrix

 1  0  1  1  1  1  1
 0  1  1  a a^7*X+a^2 a^7*X+2 a^7
 0  0 a^7*X a*X a^6*X a^5*X 2*X

generates a code of length 7 over F9[X]/(X^2) who´s minimum homogenous weight is 45.

Homogenous weight enumerator: w(x)=1x^0+168x^45+4536x^48+224x^54+17496x^56+36288x^57+336x^63

The gray image is a linear code over GF(9) with n=63, k=5 and d=45.
