On a graph, this point is sometimes named for Jordan and is the set of all vertices with minimal eccentricity.
For a Lie algebra, this term defines the set of all elements a such that, for all elements in the algebra, the commutation operation between a and any of those elements yields zero. On a graph, this point is sometimes named for Jordan and is the set of all vertices with minimal eccentricity. Euler lines by definition pass through this point of the nine-point circle. In group theory, this term applies to the members of a group that commute with every other member and is often denoted Z, while the altitudes of a triangle meet at the point called the ortho- this. For 10 points, give this name, which, in geometry defines a position whose distance from the edge of a circle is the radius, since it is exactly in the middle.
