generates a code of length 96 over Z2[X]/(X^2) who´s minimum homogenous weight is 96.

Homogenous weight enumerator: w(x)=1x^0+15x^96+32x^97+15x^98+1x^130

The gray image is a linear code over GF(2) with n=192, k=6 and d=96.
As d=96 is an upper bound for linear (192,6,2)-codes, this code is optimal over Z2[X]/(X^2) for dimension 6.
