Trilinears f(A,B,C) : f(B,C,A) : f(C,A,B), where f(A,B,C) = tan(C - A) - tan(B - A)
Barycentrics (sin A)f(A,B,C) : (sin B)f(B,C,A) : (sin C)f(C,A,B)
X(2618) lies on these lines:
1,2616 12,523 240,522 823,2633 1101,2625 2290,2622X(2618) = X(1)-Ceva conjugate of X(2616)
X(2618) = crosspoint of X(1) and X(2617)
X(2618) = crosssum of X(1) and X(2616)
