Trilinears a/f(a,b,c) : b/f(b,c,a) : c/f(c,a,b), where f(a,b,c) is as in X(218)
Barycentrics a2/f(a,b,c) : b2/f(b,c,a): c2/f(c,a,b)
X(2191) lies on these lines:
1,142 6,354 34,1458 48,1438 56,1279 106,1292 244,1253 1027,1459 1413,1456 1419,1421 2260,2279
X(2191) = cevapoint of X(I) and X(J) for these I,J: 244,663 1015,2488
X(2191) = X(I)-cross conjugate of X(J) for these I,J: 41,57 2293,6
