generates a code of length 61 over Z2[X]/(X^3) who´s minimum homogenous weight is 61.

Homogenous weight enumerator: w(x)=1x^0+32x^61+20x^62+7x^64+4x^66

The gray image is a linear code over GF(2) with n=244, k=6 and d=122.
As d=123 is an upper bound for linear (244,6,2)-codes, this code is optimal over Z2[X]/(X^3) for dimension 6.
This code was found by Heurico 1.16 in 0.125 seconds.
