generates a code of length 36 over Z2[X]/(X^2) who´s minimum homogenous weight is 34.

Homogenous weight enumerator: w(x)=1x^0+62x^34+26x^36+20x^38+2x^40+14x^42+2x^44+1x^48

The gray image is a linear code over GF(2) with n=72, k=7 and d=34.
As d=34 is an upper bound for linear (72,7,2)-codes, this code is optimal over Z2[X]/(X^2) for dimension 7.
