generates a code of length 44 over Z2[X]/(X^2) who´s minimum homogenous weight is 44.

Homogenous weight enumerator: w(x)=1x^0+56x^44+6x^48+1x^64

The gray image is a linear code over GF(2) with n=88, k=6 and d=44.
As d=44 is an upper bound for linear (88,6,2)-codes, this code is optimal over Z2[X]/(X^2) for dimension 6.
