The generator matrix

 1  0  1  1  1  1  1
 0  1 a^7*X+1  a a^7*X+a^2 a^3 a^7*X+2

generates a code of length 7 over F9[X]/(X^2) who´s minimum homogenous weight is 48.

Homogenous weight enumerator: w(x)=1x^0+504x^48+56x^54+1944x^56+4032x^57+24x^63

The gray image is a linear code over GF(9) with n=63, k=4 and d=48.
