 * Paper it was discussed in first - note on anharmonic ratio sextic??
 * 2 cartesian equations (or more)
 * applications - quantum physics? Or is that better in sinusoidal spirals?
 * Bibliography?

Two-dimensional curve?
What does "two-dimensional curve" mean? Should it be "plane curve"? Deltahedron (talk) 21:28, 10 April 2014 (UTC)

Parametric representation
The section Cayley's sextic says


 * Cayley's sextic may be parametrised (as a periodic function, period π ℝ→ℝ2) by the equations


 * x = cos3t cos 3t
 * y = cos3t sin 3t.


 * The node is at t = ±π/3.

This seems wrong in two respects. First, the equation as previously presented in Cartesian or polar form has a parameter a that is missing here. Second, according to the displayed graph, the node is at (0,0), while this says the node is at (–1/8, 0). Loraof (talk) 23:16, 22 April 2018 (UTC)
