Homogenous weight enumerator: w(x)=1x^0+6x^44+16x^45+6x^46+1x^48+2x^50 The gray image is a linear code over GF(2) with n=88, k=5 and d=44. As d=44 is an upper bound for linear (88,5,2)-codes, this code is optimal over Z2[X]/(X^2) for dimension 5. This code was found by Heurico 1.16 in 0.0095 seconds.
