Passage: As of 20 June 2019, the list identifies 32,784 triangle centers.Each point in the list is identified by an index number of the form X(n)—for example, X(1) is the incenter. The information recorded about each point includes its trilinear and barycentric coordinates and its relation to lines joining other identified points. Links to The Geometer's Sketchpad diagrams are provided for key points. The Encyclopedia also includes a glossary of terms and definitions.

Question: What kinds of coordinates were recorded from the triangles?
trilinear and barycentric
