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

Homogenous weight enumerator: w(x)=1x^0+15x^38+15x^40+1x^46

The gray image is a linear code over GF(2) with n=76, k=5 and d=38.
As d=38 is an upper bound for linear (76,5,2)-codes, this code is optimal over Z2[X]/(X^2) for dimension 5.
