Basic Parameters of the Kimberling Center X28
Given a triangle , the Kimberling center is the cevapoint of the Clawson point and the center , the homothetic center of the orthic and tangential triangles of (shown in black) .[more]

A triangle center is said to be even when its barycentric coordinates can be expressed as a function of three variables , , that all occur with even exponents. If the center of a triangle has constant barycentric coordinates, it is called a neutral center (the centroid is the only neutral center). A triangle center is said to be odd if it is neither even nor neutral.
Standard barycentric coordinates of a point with respect to a reference triangle have a sum of 1.
