generates a code of length 96 over Z2[X]/(X^2) who´s minimum homogenous weight is 98.

Homogenous weight enumerator: w(x)=1x^0+20x^98+6x^100+4x^102+1x^104

The gray image is a linear code over GF(2) with n=192, k=5 and d=98.
As d=98 is an upper bound for linear (192,5,2)-codes, this code is optimal over Z2[X]/(X^2) for dimension 5.
