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) = a[ - a2(b + c - a) + b2(c + a - b) + c2(a + b - c)]
Barycentrics af(a,b,c) : bf(b,c,a) : cf(c,a,b)
X(1486) = X(1485)-of-the-tangential-triangle
X(1486) = X(173)-of-the-tangential-triangle if ABC is acute. (Darij Grinberg, 9/22/03). See note at X(1485).
X(1486) lies on these lines:
1,159 3,142 6,692 19,25 56,1279 100,344 219,674 354,1473 513,1037X(1486) = X(7)-Ceva conjugate of X(6)
X(1486) = crosssum of X(116) and X(522)
X(1486) = crossdifference of any two points on line X(905)X(918)
