In recent years, the existence of a hadronically stable $\overline{b}\overline{b}ud$ tetraquark with quantum numbers $I({J}^{P})=0({1}^{+})$ was confirmed by first principles lattice QCD computations. this work we use to compare two frequently discussed competing structures for considering meson-meson as well diquark-antidiquark creation operators. We static-light approximation, where $\overline{b}$ quarks are assumed be infinitely heavy frozen positions, while light $u$ and $d$ fully relativistic. By minimizing effective energies solving generalized eigenvalue problems determine importance operators respect ground state. It turns out, that structure dominates $\overline{b}\overline{b}$ separations $r\ensuremath{\lesssim}0.25\text{ }\text{ }\mathrm{fm}$, whereas it becomes increasingly more irrelevant larger separations, is mostly also estimate ratio find around $60%/40%$.
