Q202 is the isogonal transform of the complement (H) of the Jerabek hyperbola (J).

(H) is also the bicevian conic C(X2, X110) hence the G-Ceva conjugate of the Brocard axis.

(H) contains X(3), X(5), X(6), X(113), X(141), X(206), X(942), X(960), X(1147), X(1209), X(1493), X(1511), X(2574), X(2575), X(2883), etc.

Q202 is a circum-quartic with double points A, B, C where the tangents are the symmedians and the perpendiculars to the Euler line.
