X(1), X(4), X(40), X(104), X(515), X(1319), X(8074)

X40-OAP points, see Table 53

The pivotal cubic K691 and the circular cubic K826 meet at four (blue) points which are the X40-OAP points. Their remaining common points are A, B, C, X(1), X(4).

The singular focus of K826 is F = X(14690), on the lines 3,214 - 40,109 - 102,165 - 117,516 - etc.

These cubics generate a pencil which contains a central cubic passing through these same nine points and also X(946), the infinite points of pK(X6, X40), the points of pK(X6, X3555) on the circumcircle.
