is this a bug ?! incorrect position of X(506)
I've been doing some amateurish 'research' on triangle centres and cubics.
To my amusement GeoGebra seems to think that X(7), X(506), X(507) is the exact same point ?!
I can be wrong, but it looks like a funny bug... Apparently GeoGebra command TriangleCenter(A, B, C, 7) shows X(7) absolutely correctly, but TriangleCenter(A, B, C, 506) and TriangleCenter(A, B, C, 507) both give the wrong result!
