Triangle Cubic

A triangle cubic is a curve that can be expressed in trilinear coordinates such that the highest degree term in the trilinears alpha, beta, and gamma is of order three.

Wells (1991) describes a cubic curve on which 37 notable triangle centers lie. Other triangle cubics include the M'Cay cubic (Gallatly 1913, p. 80) and Thomson cubic (Kimberling 1998, p. 240).
