generates a code of length 49 over Z2[X]/(X^3) who´s minimum homogenous weight is 48.

Homogenous weight enumerator: w(x)=1x^0+67x^48+48x^50+7x^52+4x^56+1x^68

The gray image is a linear code over GF(2) with n=196, k=7 and d=96.
As d=96 is an upper bound for linear (196,7,2)-codes, this code is optimal over Z2[X]/(X^3) for dimension 7.
This code was found by Heurico 1.16 in 0.0389 seconds.
