generates a code of length 16 over Z2[X]/(X^2) who�s minimum homogenous weight is 16.

Homogenous weight enumerator: w(x)=1x^0+29x^16+2x^24

The gray image is a linear code over GF(2) with n=32, k=5 and d=16.
As d=16 is an upper bound for linear (32,5,2)-codes, this code is optimal over Z2[X]/(X^2) for dimension 5.
