X(40)-Bevan point has same property. For P=X(40), Center of circle passing through G,Ga,Gb,Gc has first barycentric: (-a^6 + a^5 (b + c) - 4 a^3 (b - c)^2 (b + c) - (b - c)^4 (b + c)^2 - a^2 (b - c)^2 (b^2 - 4 b c + c^2) + a^4 (3 b^2 - 8 b c + 3 c^2) + a (b - c)^2 (3 b^3 + b^2 c + b c^2 + 3 c^3):...:...)
