generates a code of length 17 over Z2[X]/(X^2) who´s minimum homogenous weight is 10.

Homogenous weight enumerator: w(x)=1x^0+330x^10+1027x^12+2620x^14+4133x^16+4368x^18+2538x^20+1092x^22+234x^24+38x^26+3x^28

The gray image is a linear code over GF(2) with n=34, k=14 and d=10.
As d=10 is an upper bound for linear (34,14,2)-codes, this code is optimal over Z2[X]/(X^2) for dimension 14.
This code was found by Heurico 1.16 in 13.5 seconds.
