Notes

Let HaHbHc be the orthic triangle. Let HbHcA″ be the triangle similar to ABC such that segment HaA″ crosses the line HbHc, and define B″ and C″ cyclically. (Equivalently, A″ is the reflection of A in HbHc.) Let Ia be the incenter of HbHcA″, and define Ib and Ic cyclically. The lines AIa, BIb, CIc concur in X35. (Randy Hutson, November 18, 2015)
