X(3260) = P (pivot) isotomic conjugate of X(74)

harmonic associates of X(75)

isotomic conjugates of all the other points on the Neuberg cubic

K276 is the isotomic transform of the Neuberg cubic K001. It is a pK with pole X(76), the isotomic conjugate of the Lemoine point K, and pivot X(3260), the isotomic conjugate of X(74) = isogonal conjugate of the infinite point X(30) of the Euler line.

It is anharmonically equivalent to the Neuberg cubic. See Table 20.
