A triangle center P is called a "polynomial triangle center" if the trilinear coordinates of P can be expressed as polynomials in "a", "b" and "c". A triangle center P is called a "regular triangle point" if the trilinear coordinates of P can be expressed as polynomials in Δ, "a", "b" and "c", where Δ is the area of the triangle. A triangle center P is said to be a "major triangle center"
