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(2120)
Barycentrics af(a,b,c) : bf(b,c,a) : cf(c,a,b)
X(2140) lies on the cubic Z(X(101)) and these lines:
3,142 5,116 39,1086 85,514 101,2141 170,1699 218,226 244,2085X(2140) = isogonal conjugate of X(2141)
X(2140) = X(101)-Ceva conjugate of X(514)
