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) = bc(2a5 - 2a4(b + c) + 2a3bc + g(a,b,c))/(b + c),
                                    where g(a,b,c) = (b + c)(b - c)2(b + c - a)2
Barycentrics    af(a,b,c) : bf(b,c,a) : cf(c,a,b)

X(3109) lies on these lines:
1,523    2,3    11,759    12,2222    110,952    119,1793    163,1146    476,953    643,1145    691,2726    1304,2734    3080,3088
