generates a code of length 33 over Z2[X]/(X^2) who´s minimum homogenous weight is 28.

Homogenous weight enumerator: w(x)=1x^0+192x^28+168x^30+231x^32+88x^34+148x^36+120x^38+56x^40+8x^42+12x^44

The gray image is a linear code over GF(2) with n=66, k=10 and d=28.
As d=28 is an upper bound for linear (66,10,2)-codes, this code is optimal over Z2[X]/(X^2) for dimension 10.
