Trilinears u(-u/x + v/y + w/z) : v(u/x - v/y + w/z) : w(u/x + v/y - w/z), where x : y : z = X(14) and u : v : w = X(2)
Barycentrics af(a,b,c) : bf(b,c,a) : cf(c,a,b), where f(a,b,c) = u(-u/x + v/y + w/z)
X(3181) lies on these lines:
2,6 14,532 16,533 61,618 62,633 148,530 194,616 1080,1351X(3181) = reflection of X(I) in X(J) for these I,J: 299,395 617,16 622,14 3180,385
X(3181) = anticomplement of X(299)
X(3181) = X(14)-Ceva conjugate of X(2)
