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) is as given just before X(2394)
Barycentrics a/f(a,b,c) : b/f(b,c,a) : c/f(c,a,b)
X(2421) lies on the cubic K162 and these lines:

X(2421) = crosspoint of X(I) and X(J) for these (I,J): 110,805 877,2396
X(2421) = crosssum of X(I) and X(J) for these I,J: 512,2491 523,804 878,2422
