Phase portraits of coexisting infinitely many attractors in the x3 x4 plane for different initials (x1(0), x2(0), x3(0), x4(0)). (a) Asymmetric chaotic double-scroll attractors for (10−9, 0, 0, ±3.6). (b) Period-2 limit cycles for (10−9, 0, 0, ±3.3). (c) Chaotic attractors with different topologies for (10−9, 0, 0, 0) and (−1, 2, 0, 2.55). (d) Period-2 and period-3 limit cycles for (10−9, −1.5, 0, −2) and (10−9, 0, 0, −0.8). (e) Period-1 limit cycle and point attractor for (−1, 0, 0, −3.2) and (−1, 0, 0, −3.4). (f) Unbounded orbit for (−1, 2, 0, 2.2).
