X(1), X(20), X(64), X(1379), X(1380), X(3413), X(3414), X(39641), X(39642) excenters A1, B1, C1 : traces of the trilinear polar of X(3) A2, B2, C2 :cevians of X(20) M1, M2 mentioned at Q170 and their isogonal conjugates N1, N2 antipoints, see Table 77 

See Q170 for explanations. A, B, C are double points with tangents passing through X(64) and the corresponding traces of the orthic axis on the sidelines of ABC. Q171 meets the Kiepert hyperbola at 12 points : A, B, C (each twice), X(3413), X(3414), X(39641), X(39642), N1, N2. Q171 meets the Darboux cubic K004 at 18 points : A, B, C (each thrice), in/excenters, X(20), X(64), A2, B2, C2. Q171 meets the McCay cubic K003 at 18 points : A, B, C (each twice), in/excenters, X(39641), X(39642), antipoints.
