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) = sin B sin C + cos(B - C)
Barycentrics    (sin A)f(A,B,C) : (sin B)f(B,C,A) : (sin C)f(C,A,B)

X(3090) lies on these lines:
2,3    11,1058    12,1056    69,576    76,1007    110,569    155,1199    182,1614    233,1249    373,389    388,499    485,3069    486,3068    497,498    575,1352    590,1588    615,1587    748,3072    750,3073    944,1125    946,1698    1493,2888

X(3090) = inverse-in-orthocentroidal-circle of X(631)
