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 f(a,b,c) : f(b,c,a) : f(c,a,b),
where f(a,b,c) = (w/b - v/c)/a2, u : v : w = X(100)
Barycentrics g(a,b,c) : g(b,c,a) : g(c,a,b), where g(a,b,c) = (b - c)(b2 + c2 -ab - ac)
As the isogonal conjugate of a point of the circumcircle, X(918) lies on the line at infinity.
X(918) lies on these lines: 30,511 63,654 190,644 1086,1111
X(918) = isogonal conjugate of X(919)
X(918) = isotomic conjugate of X(666)
X(918) = crosssum of X(6) and X(665)
X(918) = crossdifference of any two points on line X(6)X(692) X(918) = X(514)-Hirst inverse of X(522)
