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/a)f(a,b,c) : (1/b)f(b,c,a) : (1/c)/f(c,a,b), where f(a,b,c) is as at X(1114)
Barycentrics f(a,b,c) : f(b,c,a) : f(c,a,b)
X(2581) lies on these lines:
19,27 100,1114 162,1823 240,2586 662,2577 897,2588 1821,2578 2349,2582
X(2581) = isogonal conjugate of X(2579)
X(2581) = isotomic conjugate of X(2583)
X(2581) = cevapoint of X(I) and X(J) for these I,J: 1,2579 63,2583
X(2581) = X(I)-cross conjugate of X(J) for these I,J: 2579,1 2583,92
X(2581) = X(1114)-aleph conjugate of X(1740)
