K170 is an isogonal pivotal cubic with pivot X(69) with respect to the orthic triangle. See CL019.
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.
