X(4), X(6), X(15), X(16), X(2067), X(2183), X(6502)

traces of the 6 bisectors on the sidelines of ABC

vertices of the tangential triangle

isogonal conjugates of X(370) and its five mates, see Table 10 (orange points on K001)

isogonal conjugates of the complements of X(370) and its five mates,

isogonal conjugates of the CPCC points, see Table 11 (green points on K004)

isogonal conjugates of the {X}-Cevian points of any X on the Kiepert hyperbola, see Table 28

Q190 is a circum-quartic, isogonal transform of Q034.

Note that the tangents at A, B, C are the symmedians.

Locus property

The point P, the isogonal conjugate of P and the isotomic conjugate of P, both with respect to the CEVIAN triangle of P are collinear if and only if P lies on Q074 . When CEVIAN is replaced by PEDAL, we obtain Q190 (Francisco Javier García Capitán, private message, 2024-12-08).
