The generator matrix

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

generates a code of length 6 over F9[X]/(X^2) who´s minimum homogenous weight is 40.

Homogenous weight enumerator: w(x)=1x^0+432x^40+48x^45+2592x^48+3456x^49+32x^54

The gray image is a linear code over GF(9) with n=54, k=4 and d=40.
