generates a code of length 92 over Z2[X]/(X^2) who�s minimum homogenous weight is 97.

Homogenous weight enumerator: w(x)=1x^0+4x^97+6x^98+4x^99+1x^100

The gray image is a linear code over GF(2) with n=184, k=4 and d=97.
As d=97 is an upper bound for linear (184,4,2)-codes, this code is optimal over Z2[X]/(X^2) for dimension 4.
