The generator matrix

 1  0  1  1  1  3  1  1  1  1  1  6  1  1  1  1  1  1
 0  1  7  3  4  1  8  2  6  1  5  1  0  3  6  7  4  1

generates a code of length 18 over Z9 who´s minimum homogenous weight is 36.

Homogenous weight enumerator: w(x)=1x^0+76x^36+4x^45

The gray image is a code over GF(3) with n=54, k=4 and d=36.
