X(4), X(6), X(671), X(1379), X(1380)

isogonal conjugates of X(5000), X(5001)

four foci of the Steiner in-ellipse (two real F1, F2)

infinite points of the Grebe cubic K102

A'B'C' cevian triangle of K

imaginary foci of the Brocard ellipse i.e. common points of the Brocard axis and the Kiepert hyperbola

Q094 is the isogonal transform of the quartic Q019. These two curves are related with {X}-Pedal and {X}-Antipedal points as in Table 45.

More precisely, for any strong center X on the Grebe cubic K102, the {X}-Pedal points lie on Q094. For example, the {X(6)}-Pedal points are the four foci of the Steiner in-ellipse.

Q094 is a circular quintic with focus the Lemoine point K. The three other asymptotes are parallel to those of the Grebe cubic K102.

A, B, C are nodes and the tangents at A are AK and the parallel to BC.

Q094 is the locus of point M such that K, M and the isogonal conjugate of M with respect to the circumcevian triangle of M are collinear. See a generalization in the page Q050.
