K170 is an isogonal pivotal cubic with pivot X(69) with respect to the orthic triangle. See CL019.
Its complement is K168 = pK(X3, X2).
K170 and K200 meet at A, B, C, X(2), Ga, Gb, Gc and two other points with first barycentric coordinate sec(A) ± tan(A). These points are isotomic conjugates and lie on the line X(4), X(8). See ADGEOM, #3773 & sq., 2017-04-27.
K170 and pK(X6, X12272) meet at six points on the circumcircle and three other (not always all real) points on the line X(6), X(1196), X(2056), X(3167), etc.
