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

Parametric representation edit
The section Cayley's sextic#Equations of the curve 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)
