generates a code of length 32 over Z3[X]/(X^2) who´s minimum homogenous weight is 63.
Homogenous weight enumerator: w(x)=1x^0+160x^63+72x^66+10x^72
The gray image is a linear code over GF(3) with n=96, k=5 and d=63.
As d=63 is an upper bound for linear (96,5,3)-codes, this code is optimal over Z3[X]/(X^2) for dimension 5.
