4D Rössler hyperchaotic system with two positive Lyapunov exponents --- qualitatively different from standard chaos, simultaneous expansion in two directions
Standard analysis sees: no strongly notable standard properties. The atlas additionally detects multi-frequency phase coupling. It sits beside EEG Seizure in the atlas (standard-bank rank 89) — a neighbor conventional features miss.
