The generator matrix

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

generates a code of length 5 over F9[X]/(X^2) who´s minimum homogenous weight is 27.

Homogenous weight enumerator: w(x)=1x^0+80x^27+3240x^32+240x^36+29160x^40+25920x^41+408x^45

The gray image is a linear code over GF(9) with n=45, k=5 and d=27.
