generates a code of length 31 over Z2[X]/(X^2) who´s minimum homogenous weight is 32.

Homogenous weight enumerator: w(x)=1x^0+31x^32

The gray image is a linear code over GF(2) with n=62, k=5 and d=32.
As d=32 is an upper bound for linear (62,5,2)-codes, this code is optimal over Z2[X]/(X^2) for dimension 5.
