Trilinears f(a,b,c) : f(b,c,a) : f(c,a,b), where f(a,b,c) is as described just before X(2883)
Barycentrics af(a,b,c) : bf(b,c,a) : cf(c,a,b)
X(2915) lies on these lines:
2,3 35,37 36,1104 40,2778 500,1790 511,1437 1603,1604 1780,2245
X(2915) = midpoint of X(1717) and X(2960)
X(2915) = X(321)-Ceva conjugate of X(6)
X(2915) = crosspoint of X(100) and X(250)
X(2915) = crosssum of X(125) and X(513)
