Sprott–Linz Case M — dx/dt = −z, dy/dt = −x² − y, dz/dt = a + b·x + y. Classic chaotic a=1.70 b=1.70. Distinct from Case L (y+a·z, b·x²−y, 1−x), Case K (x·y−z, x−y, x+a·z), Case J (a·z, −a·y+z, −x+y), Case I (−a·y, x+z, x+y²−a·z), Case H (−y+z², x+a·y, x−b·z), Case G (a·x+b·z, xz−y, −x+y), Case F (y+z, −x+a·y, x²−b·z), Case E (yz, x²−y, 1−a·x), Case D (−y, x+z, xz+a·y²), Case C (yz, x−y, α−x²), Case B (yz, x−y, α−xy), Case A (y, −x+y·z, a−y²), and Lorenz-84.
