Notes

As a point on the Euler line, X3526 has Shinagawa coefficients \((5, -1)\).

Let AeBeCe and AiBiCi be the Ae and Ai triangles (aka K798e and K798i triangles). Let A'B'C' be the medial-of-medial triangle. X3526 is the radical center of the circumcircles of triangles A’AeAi, B’BeBi, C’CeCi. (Randy Hutson, June 7, 2019)
