nP-n-L1: nL-MVP Eulerline

The nL-MVP Eulerline is the line connecting collinear points nP-n-P1, nP-n-P2, nP-n-P3, nP-n-P4, being the MVP-Centroid, Circumcenter, Orthocenter and Nine-point Center in an n-Point. For an explanation of MVP-points see nP-n-Luc1.
Next figure gives an example of nP-n-L1 in a 4-Point.

Correspondence with ETC/EQF:

When n=3, then nP-n-L1 = Triangle Eulerline X(3).X(4), with
• 3P-n-P1 = 3P-MVP Centroid = X(2)
• 3P-n-P2 = 3P-MVP Circumcenter = X(3)
• 3P-n-P3 = 3P-MVP Orthocenter = X(4)
• 3P-n-P4 = 3P-MVP Nine-point center = X(5)
When n=4, then nP-n-L1 = Quadrilateral Eulerline QA-P1.QA-P32.QA-P33, with
• 4P-n-P1 = 4P-MVP Centroid = QA-P1 (QA-Centroid)
• 4P-n-P2 = 4P-MVP Circumcenter = QA-P32 (Centroid Circumcenter Quadrangle)
• 4P-n-P3 = 4P-MVP Orthocenter = QA-P33 (Centroid Orthocenter Quadrangle)
• 4P-n-P4 = 4P-MVP Nine-point center = Midpoint (QA-P32,QA-P33)
