Trilinears f(a,b,c) : f(b,c,a) : f(c,a,b) (see note above X(1512))
X(1560) lies on the nine-point circle and these lines:
2,112 4,111 6,67 53,136 115,427 122,216 135,571 187,468
X(1560) = complement of X(2373)
X(1560) = X(2)-Ceva conjugate of X(468)
X(1560) = crosspoint of X(2) and X(858)
X(1560) = crosssum of X(6) and X(1177)
