generates a code of length 36 over Z2[X]/(X^2) who´s minimum homogenous weight is 32.

Homogenous weight enumerator: w(x)=1x^0+45x^32+76x^34+46x^36+40x^38+28x^40+12x^42+2x^44+4x^48+2x^56

The gray image is a linear code over GF(2) with n=72, k=8 and d=32.
As d=32 is an upper bound for linear (72,8,2)-codes, this code is optimal over Z2[X]/(X^2) for dimension 8.
