generates a code of length 16 over Z2[X]/(X^2) who�s minimum homogenous weight is 12.

Homogenous weight enumerator: w(x)=1x^0+80x^12+112x^14+141x^16+96x^18+64x^20+16x^22+2x^24

The gray image is a linear code over GF(2) with n=32, k=9 and d=12.
As d=12 is an upper bound for linear (32,9,2)-codes, this code is optimal over Z2[X]/(X^2) for dimension 9.
This code was found by Heurico 1.16 in -3.24e-008 seconds.
