generates a code of length 43 over Z2[X]/(X^2) who´s minimum homogenous weight is 41.

Homogenous weight enumerator: w(x)=1x^0+36x^41+28x^42+28x^44+24x^45+3x^46+3x^48+4x^49+1x^62

The gray image is a linear code over GF(2) with n=86, k=7 and d=41.
As d=41 is an upper bound for linear (86,7,2)-codes, this code is optimal over Z2[X]/(X^2) for dimension 7.
