Let A'B'C' be the circumcevian triangle of a point P, and Ab, Ac, Bc, Ba, Ca, Cb the circumcenters de PA'B, PA'C, PB'C, PB'A, PC'A, PC'B. These six points lie in a conic. When P is an intersection between the Euler line and the circle orthogonal to the circumcircle and centered at X(468), the conic is a circle.
