generates a code of length 93 over Z2[X]/(X^2) who´s minimum homogenous weight is 92.
Homogenous weight enumerator: w(x)=1x^0+72x^92+32x^94+19x^96+3x^104+1x^136
The gray image is a linear code over GF(2) with n=186, k=7 and d=92.
As d=92 is an upper bound for linear (186,7,2)-codes, this code is optimal over Z2[X]/(X^2) for dimension 7.
