Notes

Let TanaTanbTanc be the tangential triangle of ABC, and let L be the line through X1 parallel to BC. Let A″ = L∩TanbTanc, and define B″ and C″ cyclically. Let A* = TanbB″∩TancC″, and define B* and C* cyclically. The lines AA*, BB*, CC* concur in X*(3445), and the lines TanaA*, TanbB*, TancC* concur in X3052. (Angel Montesdeoca, April 29, 2016)
