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 (y + z) sec A : (z + x) sec B : (x + y) sec C, x : y : z = X(72)
Barycentrics (y + z) tan A : (z + x) tan B : (x + y) tan C, x : y : z = X(72)
X(1842) lies on these lines:
4,9 25,225 28,36 29,1848 33,976 34,207 51,65 92,1891 278,1420 1737,1782 1829,1831 1878,1888X(1842) = X(4)-Ceva conjugate of X(1834)
X(1842) = crosspoint of X(27) and X(1119)
X(1842) = crosssum of X(71) and X(1260)
