A point triplet, also known as the discrete space of three points, is a shape made up of three disconnected points. It can be thought of as the vertices of a triangle. Its most natural embedding is in two dimensions, where the three points make up the vertices of a triangle, but it also has a one-dimensional embedding as three points in a line. It can be considered as a subset of the real line with the subspace topology comprising three disconnected elements (for example, {0, 1, 2}).
