This is also X(66) of the medial triangle.
X(206) lies on these lines:
2,66 5,182 6,25 26,511 69,110 157,216 160,577 219,692 237,571
X(206) = midpoint of X(I) and X(J) for these (I,J): (6,159), (110,1177)
X(206) = complement of X(66)
X(206) = complementary conjugate of X(427)
X(206) = X(2)-Ceva conjugate of X(32)
X(206) = crosspoint of X(2) and X(315)
X(206) = crosssum of X(339) and X(523)
