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(596)
Barycentrics a2/f(a,b,c) : b2/f(b,c,a): c2/f(c,a,b)
X(2220) lies on these lines:
3,6 31,872 37,82 172,1100 560,692 604,1415 609,1449 906,1743 1918,2210 2174,2251
X(2220) = X(I)-Ceva conjugate of X(J) for these I,J: 765,692 849,31
X(2220) = crosspoint of X(163) and X(1252)
X(2220) = crosssum of X(1086) and X(1577)
