K298 = DF(X23) is a focal DrozFarny cubic, a member of the class CL039. Its singular focus is K, the Lemoine point. The real asymptote is the parallel at X(599) to the Euler line. It meets the focal tangent at X = X(14906) whose isogonal conjugate X(14907) is the intersection of the lines {2, 187}, {3, 315}, {4, 1078}, {20, 76}, {30, 183}, etc. K298 meets the Steiner ellipse again at S1, S2 lying on the trilinear polar of X(2373).
