$\mathbf{F}_2^{12}$$\mathrm{GF}(2^{12})$ is isomorphic, as an abelian group, to $\mathbf{F}_{2^6}^2$. Viewed as a two-dimensional vector space over $\mathbf{F}_{2^6}$, each$\mathrm{GF}(2^6)$. The one-dimensional subspace containssubspaces are all disjoint $0$(barring the zero vector), and $63$ other vectorscontain 63 nonzero elements each.
