Trilinears f(a,b,c) : f(b,c,a) : f(c,a,b), where f(a,b,c) = (1 - cos A)u(a,b,c), where u : v : w = X(43)
Barycentrics af(a,b,c) : bf(b,c,a) : cf(c,a,b)
X(1403) lies on these lines:
1,3 2,1284 6,893 31,1428 42,1469 43,1423 75,183 109,727 1326,1412X(1403) = X(604)-Ceva conjugate of X(56)
X(1403) = X(1423)-cross conjugate of X(56)
X(1403) = X(31)-Hirst inverse of X(1428)
