generates a code of length 41 over Z2[X]/(X^2) who´s minimum homogenous weight is 38.

Homogenous weight enumerator: w(x)=1x^0+84x^38+76x^40+40x^42+24x^44+10x^46+7x^48+6x^50+4x^52+2x^54+2x^58

The gray image is a linear code over GF(2) with n=82, k=8 and d=38.
As d=38 is an upper bound for linear (82,8,2)-codes, this code is optimal over Z2[X]/(X^2) for dimension 8.
