Table 19-1 gives a list of triangles whose vertices lie on the Neuberg cubic K001 (P* is the isogonal conjugate of P). Other points are mentioned in Table 10 (points related to X370) and Table 18 (Ua, Ub, Uc and related points).

Table 19-2 gives the perspectors of these triangles which also lie on the Neuberg cubic (P/Q denotes a cevian quotient).

Table 19-3 gives the sixth common point S of the circumcircle of a triangle with the Neuberg cubic. See also Table 27.

Table 19-4 gives the tangentials of centers listed in ETC.

See the related paper Perspective Triangles inscribed in the Neuberg Cubic.

Table 19-2 : the cells in yellow contain centers listed in ETC, those in green were added in June 2014 (centers X5667-X5685), those in pink and light blue were added in October 2015 (centers above X7000). The remaining white cells were filled up in November 2015 with a good help from Peter Moses.

If UVW is one of the 25 triangles above, the tangents at its vertices to the Neuberg cubic concur at T hence the polar conic of T passes through T (counted twice), U, V, W and a 6th point M which is the isogonal conjugate of the perspector of the reference triangle ABC and UVW.

If U', V', W' are the third intersections of K001 with the sidelines of UVW then M is the common point of the lines UU', VV', WW'.

It follows that K001 is a pK with pivot M, isopivot T with respect to UVW.

The circumcircle of UVW meets K001 at a 6th point S which lies on the line through M and T*. S is also the common point of the lines UU'*, VV'*, WW'*.

Example : UVW = TR9,

M = X74, T = X2132, T* = X2133, S = X5676.
