Cosmin Pohoata, On the Euler reflection point,
Forum Geometricorum, 10 (2010) 157--163.

Abstract.  The Euler reflection point E of a triangle is known in literature as the common point of the reflections of its Euler line OH in each of its sidelines, where O and H are the circumcenter and the orthocenter of the triangle, respectively. In this note we prove that E lies on six circles associated with the triangles of Napoleon.
