generates a code of length 38 over Z2[X]/(X^2) who´s minimum homogenous weight is 36.

Homogenous weight enumerator: w(x)=1x^0+54x^36+32x^38+29x^40+10x^44+1x^48+1x^56

The gray image is a linear code over GF(2) with n=76, k=7 and d=36.
As d=36 is an upper bound for linear (76,7,2)-codes, this code is optimal over Z2[X]/(X^2) for dimension 7.
