Abstract:	In this Letter we show numerical existence of O(4) $O (4)$ Dirac–Born–Infeld (DBI) Textures living in (N+1) $(N + 1)$ dimensional spacetime. These defects are characterized by S^N→S³ $S^{N} \to S^{3}$ mapping, generalizing the well-known Hopf fibration into _π_N(S³) $π_{N} (S^{3})$ , for all N>3 $N > 3$ . The nonlinear nature of DBI kinetic term provides stability against size perturbation and thus renders the defects having natural scale.
