You can move the points A, B and C (click on the point and drag it).
Press the keys “+” and “−” to zoom in or zoom out the visualization window and use the arrow keys to translate it.
You can also construct all centers related with this one (as described in ETC) using the “Run Macro Tool”. To do this, click on the icon , select the center name from the list and, then, click on the vertices A, B and C successively.

Trilinears 1/f(a,b,c) : 1/f(b,c,a) : 1/f(c,a,b), where f(a,b,c) : f(b,c,a) : f(c,a,b) = X(103)
Barycentrics a/f(a,b,c) : b/f(b,c,a) : c/f(c,a,b)
As the isogonal conjugate of a point on the circumcircle, X(516) lies on the line at infinity.
X(516) lies on these lines:
1,7 2,165 3,142 4,9 8,144 30,511 35,411 55,226 57,497 65,950 80,655 100,908 102,929 103,927 118,910 200,329 238,673 354,553 355,382 376,551 993,1012
X(516) = orthopoint of X(514)
X(516) = isogonal conjugate of X(103)
X(516) = anticomplementary conjugate of X(152)
X(516) = complementary conjugate of X(118)
X(516) = X(4)-Ceva conjugate of X(118)
X(516) = crosssum of X(I) and X(J) for these (I,J): (3,916), (55,672)
X(516) = crossdifference of any two points on line X(6)X(657)
