generates a code of length 25 over Z2[X]/(X^2) who´s minimum homogenous weight is 24.

Homogenous weight enumerator: w(x)=1x^0+14x^24+32x^25+14x^26+1x^32+2x^34

The gray image is a linear code over GF(2) with n=50, k=6 and d=24.
As d=24 is an upper bound for linear (50,6,2)-codes, this code is optimal over Z2[X]/(X^2) for dimension 6.
