Information from Kimberling's Encyclopedia of Triangle Centers

Trilinears            f(a,b,c) : f(b,c,a) : f(c,a,b), where f(a,b,c) = a2(b + c)(b - c)2
Barycentrics    af(a,b,c) : bf(b,c,a) : cf(c,a,b)

X(3121) lies on these lines:
81,893    100,292    244,665    351,865    890,1977    1402,2205

X(3121) = X(I)-Ceva conjugate of X(J) for these I,J: 37,512    213,798    274,513    893,649    1015,3122    1333,667    1402,669    2203,1980
X(3121) = crosspoint of X(I) and X(J) for these I,J: 37,512    42,649    213,798    274,513    667,1333
X(3121) = crosssum of X(I) and X(J) for these I,J: 81,99    86,190    100,213    274,799    314,645    321,668

X(3121) = crossdifference of every pair of points on the line X(99)X(100)
