X(2), X(3), X(6), X(69), X(485), X(486), X(8770)
X(2)-Ceva conjugate of X(69)
CPCC or H-cevian points, see Table 11
foci of the K-ellipse (inellipse with center K when the triangle ABC is acute angle)
It is also the locus of point P such that P, GSC(P), X(6) are collinear. GSC is defined here.
It has the same asymptotic directions as pK(X6, X193) and K170 = pK(X2, X4) which is actually its anticomplement.
It meets the circumcircle at the same points as pK(X6, X69) = K169 and the Steiner circum-ellipse at the same points as pK(X2, X76) = K141. It is tangent at O to the Brocard line, at G to the Euler line.
K168 is an isogonal pK with pivot X(6) with respect to the complement of the orthic triangle.
