Trilinears f(a,b,c) : f(b,c,a) : f(c,a,b), where f(a,b,c) = (J2 + 1) cos A - 2 cos B cos C, where J is as at X(1113)
Barycentrics af(a,b,c) : bf(b,c,a) : cf(c,a,b)
X(2071) lies on these lines: 2,3 64,2063 74,323 99,1236 476,1294 477,925 691,1297 1290,1295
X(2071) = reflection of X(I) in X(J) for these (I,J): (4,2072), (23,186), (186,3)
X(2071) = inverse-in-circumcircle of X(20)
X(2071) = anticomplement of X(403)
