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.

For the definition of orthocorrespondent, see the notes just before X(1992).
X(1331) lies on thes lines:
63,212 71,895 72,283 78,255 100,109 101,110 145,595 162,190 228,295 287,293 394,1260 677,1252 901,1293
X(1331) = X(I)-Ceva conjugate of X(J) for these (I,J): (190,101), (643,100)
X(1331) = X(I)-cross conjugate of X(J) for these (I,J): (521,283), (652,63), (1260,1252)
X(1331) = cevapoint of X(I) and X(J) for these (I,J): (3,1459), (72,521), (212,652)
