X₃₈₅₆ (X₃₆₂₈com(EULER TRIANGLE)) constructed on acute reference triangle \((a, b, c) = (5, 6, 7)\) with unit baseline AB = \(1\).

Constructed Elements

• Central Lines: {2, 3} (Euler line)

• Related Centers: X₂ (CENTROID), X₃ (CIRCUMCENTER), X₄ (ORTHOCENTER)

Barycentrics: \(f(a,b,c) : f(b,c,a) : f(c,a,b)\), where \(f(a,b,c) = 6a^{4} - 11b^{4} - 11c^{4} + 5a^{2}b^{2} + 5a^{2}c^{2} + 22b^{2}c^{2}\)
