Trilinears f(a,b,c) : f(b,c,a) : f(c,a,b), where f(a,b,c) = - (cos A)/x + (cos B)/y + (cos C)/z, x : y : z = X(37)
Barycentrics af(a,b,c) : bf(b,c,a) : cf(c,a,b)
X(1719) lies on these lines:
1,1790 10,191 19,1707 27,1733 46,407 165,846 1709,1744X(1719) = X(1826)-Ceva conjugate of X(1)
X(1719) = X(I)-aleph conjugate of X(J) for these (I,J): (4,579), (1826,1719)
