Homogenous weight enumerator: w(x)=1x^0+91x^92+30x^96+2x^100+1x^108+1x^112+2x^116 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. This code was found by Heurico 1.16 in 1.72 seconds.
