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) is as given just before X(2677) using P = X(74), U = X(101)
Barycentrics af(a,b,c) : bf(b,c,a) : cf(c,a,b)
X(2688) lies on the circumcircle and these lines:
3,2690 27,1304 30,101 74,514 74,514 103,523 107,2073 110,516 112,1886 1305,2071X(2688) = reflection of X(2690) in X(3)
X(2688) = isogonal conjugate of X(2772)
