Trilinears            f(a,b,c)) : f(b,c,a) : f(c,a,b), where f(a,b,c) = bc cos2A - a2cos B cos C - sqrt(3)(ab sin B + ac sin C)
Barycentrics    af(a,b,c) : bf(b,c,a) : cf(c,a,b)

X(3107) is the center of the equilateral triangle introduced at X(3105).

X(3107) lies on these lines:
3,6    13,2782    14,262    17,76       194,628

X(3107) = midpoint of X(3105) and X(3106)
X(3107) = reflection of X(I) in X(J) for these I,J: 3105,3106    3106,39
