generates a code of length 33 over Z2[X]/(X^3) who´s minimum homogenous weight is 32.

Homogenous weight enumerator: w(x)=1x^0+189x^32+64x^36+2x^48

The gray image is a linear code over GF(2) with n=132, k=8 and d=64.
As d=64 is an upper bound for linear (132,8,2)-codes, this code is optimal over Z2[X]/(X^3) for dimension 8.
This code was found by Heurico 1.16 in 9.37 seconds.
