Trilinears            f(a,b,c) : f(b,c,a) : f(c,a,b), where f(a,b,c) = bc/(2bc - ab - ac)
Barycentrics    af(a,b,c) : bf(b,c,a) : cf(c,a,b)

Trilinears for X(3227) are obtained by applying the symbolic substitution (a,b,c)-->(bc,ca,ab) to trilinear coordinates of X(106). As a symbolic substitution, this mapping takes circumconics to circumconics. In particular, it maps circumcircle onto the Steiner circumellipse, which passes through X(3227).

X(3227) lies on these lines:
1,190    2,668    28,648    57,664    81,99    88,239    105,666    274,670    291,519    335,2087    671,2787    903,1022    957,1992

X(3227) = isogonal conjugate of X(3230)
X(3227) = isotomic conjugate of X(536)
