X(1), X(2), X(4), X(65), X(69), X(69), X(75), X(81), X(314), X(321), X(1764) vertices of the antimedial triangle 

K254 is the isotomic pK with pivot X(314), the isotomic conjugate of X(65) = orthocenter of the intouch triangle. It is the isogonal transform of K430 = pK(X32, X21) and the anticomplement of K253. K254 is the locus of pivots of all pK which have the same asymptotic directions as pK(X6, X81) and K253. See "Asymptotic Directions of Pivotal Isocubics" in the downloads page.
