X(1), X(8), X(40), X(175), X(176), X(188), X(280), X(483)
CPCC or H-cevian points, see Table 11
Its asymptotes are parallel to those of K1086 = pK(X6, X145).
It meets the circumcircle at the same points as pK(X6, X3869).
Its isogonal transform is K632 = pK(X604, X1) and its isotomic transform is pK(X85, X75).
More generally, any pK with pivot X(8) and pole on the line through X(2), X(7), X(9), ... contains the Soddy centers.
