generates a code of length 19 over Z2[X]/(X^2) who´s minimum homogenous weight is 12.

Homogenous weight enumerator: w(x)=1x^0+215x^12+584x^14+1282x^16+1976x^18+2074x^20+1272x^22+612x^24+136x^26+39x^28+1x^32

The gray image is a linear code over GF(2) with n=38, k=13 and d=12.
As d=12 is an upper bound for linear (38,13,2)-codes, this code is optimal over Z2[X]/(X^2) for dimension 13.
This code was found by Heurico 1.16 in 1.11 seconds.
