generates a code of length 48 over Z2[X]/(X^2) who´s minimum homogenous weight is 48.

Homogenous weight enumerator: w(x)=1x^0+124x^48+3x^64

The gray image is a linear code over GF(2) with n=96, k=7 and d=48.
As d=48 is an upper bound for linear (96,7,2)-codes, this code is optimal over Z2[X]/(X^2) for dimension 7.
