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(38)
Barycentrics af(a,b,c) : bf(b,c,a) : cf(c,a,b)
X(1401) lies on these lines:
7,310 43,57 51,244 56,58 65,519 226,1463 354,1122 511,982 1106,1425 1355,1365 1356,1366 1402,1458 1407,1460
X(1401) = crosspoint of X(7) and X(56)
X(1401) = crosssum of X(8) and X(55)
