generates a code of length 56 over Z2[X]/(X^2) who´s minimum homogenous weight is 52.

Homogenous weight enumerator: w(x)=1x^0+221x^52+146x^56+84x^60+37x^64+15x^68+8x^72

The gray image is a linear code over GF(2) with n=112, k=9 and d=52.
As d=52 is an upper bound for linear (112,9,2)-codes, this code is optimal over Z2[X]/(X^2) for dimension 9.
