The generator matrix

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

generates a code of length 15 over Z9 who´s minimum homogenous weight is 28.

Homogenous weight enumerator: w(x)=1x^0+6x^28+12x^29+38x^30+12x^31+6x^32+2x^33+4x^36

The gray image is a code over GF(3) with n=45, k=4 and d=28.
