The generator matrix

 1  1  1  1  1  1  1  1  1
 0  5  0  5 10 10  0  5 10
 0  0  5 15 10 15 10  5  0

generates a code of length 9 over Z25 who´s minimum homogenous weight is 30.

Homogenous weight enumerator: w(x)=1x^0+32x^30+48x^35+500x^36+24x^40+20x^45

The gray image is a code over GF(5) with n=45, k=4 and d=30.
