generates a code of length 33 over Z2[X]/(X^2) who´s minimum homogenous weight is 32.

Homogenous weight enumerator: w(x)=1x^0+108x^32+18x^40+1x^48

The gray image is a linear code over GF(2) with n=66, k=7 and d=32.
As d=32 is an upper bound for linear (66,7,2)-codes, this code is optimal over Z2[X]/(X^2) for dimension 7.
This code was found by Heurico 1.16 in 20.6 seconds.
